I would be curious to know what it’s like to be a Jewish person in Wyoming. Maybe I can ask him.
People who have lived in cities for a long time don’t often function well in more sparsely populated areas. It sounds idyllic, but the lack of amenities and few choices of entertainment, restaurants, services and the like gets old very quickly. If this person doesn’t need to have employment, I’d suggest going to Wyoming and renting a place for a month or two in, say, February.
Again, it would depend on where you are living in Montana. A quick search shows only 5 synagogues in Wyoming; 2 in Jackson and 1 each in Casper, Cheyenne, and Laramie. So living outside the largest cities you’re not going to encounter too many observant Jews if that’s your goal.
Never encountered snow in August — mid-September is the earliest I recall — but one year “campus day” (a day in May when the student body was turned out to give the grounds a spring cleaning) turned into a campus-wide snowball [DEL]fight[/DEL] war. Including several rather substantial forts.
I will say that the snow was much more powdery (and easier to drive in) than what we get in the western SoW. But when the wind piles it up above the sill of your car door, it do discourage casual trips.
Internet access can be a serious problem in rural areas, although I don’t know the specifics about Wyoming.
This comment should not be discounted.
My brother lived there for many years. He would tell of waking up in the morning to a foot of snow and then coming home after work to it all gone. Did it melt? No, it just blew away. Same with the lawn he kept trying to plant. He was probably exaggerating a little when he said that the wind never stops blowing there.
What I don’t get about the OP’s friend, is why go from one extreme to the other?
From urban NE to quite literally the middle of nowhere?
There are plenty of rural stretches in the eastern/midwestern US that seem like a more reasonable compromise.
In July of 1976 I took a Greyhound Bus from Pittsburgh to Sacramento. At 3 am I found myself in Cheyenne. I walked outside the bus station and there were banners for Cheyenne Days, but no people.
After stretching my legs for 5 minutes, I returned to the bus station and continued west. I’d seen enough of Cheyenne.
From an old tee shirt I had when I lived in Cheyenne:
“Wyoming Wind Festival
Jan 1 - Dec 31”
I think you can still get that shirt in town.
Never been to Livingstone, MT, have you? People walk with a permanent lean, and when the wind from The Grand Canyon of the Yellowstone occasionally stops, everyone falls down.
According to John MacPhee in Rising From The Plains, which is about Wyoming geology, I-80 through the state has been closed by snow every month of the year save August.
Speaking from personal experience, one of my great life memories is cooking hash browns over a camp stove in the middle of a snowstorm. On the Fourth of July.
Granted, that was atop a 10,000 foot mountain in the Wind Rivers, but still…
I appreciate you giving a real response to my dopey joke. 
Hey, I actually know a Jew living in Jackson.
I remember in 1985 or 6 it was the first day of summer and the weather guy said montana and WY was going to be 25 degrees and snowing ……
sounds like they get as much wind as we do …….
On our trip across the country we stopped in Rock Srpings for the night. They have an awesome community college (Western Wyoming CC) which has dinosaur skeletons, an art gallery, slices of rock showing fossils, and an Easter Island like statue the students erected to see how it was done. Nicest community college we ever saw. We asked the receptionist for a dinner recommendation and got a great one in a hotel. Oh, the college exhibits are free and open in the evening.
I’m not sure about staying there a week, but one night was great.
Laramie is a nice town. Lots of lilacs in the spring. Lots of empty miles on all sides.
Gets cold and windy on occasion. They’ve some decent restaurants, and a co-op. University of WY adds some culture to the place. Not a lot of trees outside town, but some nice mountains. If lonely drives you nuts, Wyoming is not the place for you. Otherwise it’s not bad at all. Certainly not overcrowded.
I lived in Laramie for 43 years. I feel confident in saying there is NOT an actual Synagogue in Laramie. The Episcopal church allows one of their facilities to be used for Jewish services. There is an actual Mosque, I presume thanks to Moslems attending the University of Wyoming.
For a long time I thought we were complaining about the weather just to keep the place from becoming overpopulated. But recently someone tallied all the extreme weather events in the US and determined that Laramie does actually have the worst weather in the US.
Just because - here’s my favorite song about Wyoming from one of my favorite folk singers.
I can only comment on WY from having visited a few times, driving, in the summer. Perhaps the most beautiful place in the US, IMO, even including the Powder River basin (coal area in the northeast). I loved pretty much all the varied landscapes in WY that I saw. And people were nice, that I met.
But as native NY’er (now in NJ nearby) I’d be really cautious deciding to live there. That’s not any negative statement about WY, but just the risk it wouldn’t be a long term fit for me, it’s so different. Plus as I mentioned I haven’t wintered there. I’m not one of those people for whom everything is political so that wouldn’t be a big factor either way. Also I question whether it’s fair to assume one would encounter any more prejudice due to their background in a place like WY than NJ, I’m just not sold on that idea, as popular as it tends to be in places like NJ. OTOH say you were an immigrant, lived in/near an immigrant community in NJ (supermarkets/restaurants with the native food, make friends in the community, etc) then moved to WY. That’s a real difference I think.
When I saw this, my first reaction is “nice place to visit, but you wouldn’t want to live there.”
I also recommend “City Data” for more detailed info.
