Re Ben and Jerry’s: I’ve now been there 4 (yes, FOUR) times. Once as a side jaunt when taking my daughter to visit colleges. Another time when our family was travelling from NH to Montreal. A third time when I was taking my daughter on another trip and it was not far out of the way. And a fourth time when I was with a bunch of friends, who decided to go there.
One visit would honestly have been plenty. And it’s really not worth going more than 20 minutes out of the way. Yeah, it’s sort of cool to see the factory in operation (if it is; it usually isn’t, on weekends), but not a can’t-miss experience.
Acadia is nice. We went there a couple summers back. I wish we’d stayed closer to the park (we were a 40ish minute drive). The bus drive around the park is good, though in hindsight the day we did that would have been a better day to drive ourselves, as it was a nice sunny day and we might have enjoyed doing more walking than the next day. Don’t plan on swimming in the ocean though - it is something like 55 degrees!
Mount Washington is worth a trip, if it’s not far out of the way. The cog railway is worth it! We were near there for a family reunion. Several relatives DROVE up the mountain, which I gather was a bit terrifying. And the weather was completely different at the top - freezing (literally), and the wind was so strong my hair was blowing into my face and I couldn’t see anything.
Moose: We finally got to see moose, after several years of trips to the Northeast and seeing “moose crossing” signs but no critters. We had been in Quebec City, and intentionally took very rural roads to cross into the US at the only New Hampshire border crossing, and thus drove down “Moose Alley”: US Route 3, approaching Pittsburg, NH. We saw a cow moose browsing by the side of the road. She seemed unimpressed by the cars that had pulled over to take a photo.
We saw a second one about an hour later, when driving west on Vermont 114 (parallels the Canadian border).
Prior to that trip, the last moose we had ever seen was in 1985, when a bull moose strolled right through our campsite at Grand Teton.
To be fair, north of Pittsburg there IS some New Hampshire - 10ish miles of a whole lot of nothing.
There isn’t much more than that on the Quebec side of the border - when we did our drive, it was small town… 5 miler of nothing… tiny town… 5 miles of nothing… some gravel roads… I do wish we’d stopped to experience the magnetic hill near there (Chartierville, I think).
