Preferably of a pleasant disposition. early July, near Marlborough, Mass. Do you have one I may borrow or rent for a day?
Assuming this is a serious request, you need an animal wrangler.
You can do an online search of your own but I did a quick one and found William Berloni Theatrical Animals, Inc.
Bactrian, or dromedary?
You might have to walk a mile for one.
I did not think you were that old… 
I need a camel too. I didn’t realize that I needed one before you posted this thread, but upon further consideration, I must have one!
I’m sorry to report that on the whole, camels are a dour lot. Not particularly dangerous or aggressive, but stubborn and unfriendly.
(I speak of dromedaries. I don’t know anything about bactrians.)
You could start with this and go from there
And I need a camel toe.
I was going to suggest that regardless of location and time the OP’s wish for a pleasant dispositon was dooming this request to failure.
Oh god, no! We ride the camel to the brothel!
Filtered or unfiltered?
[I think I originally heard this joke here so credit to whoever’s joke I’m stealing]
An old retired guy in Miami decides that he wants a camel. He orders one, it arrives and he’s delighted. He gets on its back and spends the day tromping through the neighborhood waving to everyone and basically acting like this is the greatest thing in the world.
Next morning, he goes outside and the camel’s gone. He calls the police and the officer starts taking notes. “Can you tell me how tall the camel was?”
“No, I only had it for one day. I never measured it.”
“Can you tell me how much it weighed?”
“No, I only had it the one day. I never weighed it.”
Exasperated, the cop asks “Can you at least say if it was a boy or girl?”
“YES!” the man cries, “It was a BOY!”
The cop says “You sound really confident of this.”
The man says “All day when I was riding it, everyone kept saying ‘Hey, get a load of the schmuck on that camel!’”
An englishman an irishman and a scotsman were in the sweltering desert walking around looking desperatly for something to eat and drink, when, as if out of nowhere, a camel appeared. The englishman caught the camel and spluttered I support “Liverpool, so I suppose I better eat the liver.” The scotsman immediately shouted, “Well I support Hearts so I’ll eat the heart.” And then the irishman said, “I support Arsenal, but I don’t feel hungry any more.”
Isosleepy, Good luck in your camel quest.
bismillah! that prancing video will take lifetimes to un-see!
The camel is for a costume party. The SO claims I don’t always make enough effort, so I’ll show her.
I’m going as Lawrence of Arabia, so a camel would make for a nice completion of the costume I think. Unless it bites, hence the request for a sunny disposition. I know pretty much all camels bite, but maybe there’s one non-biting camel out there, and maybe it happens to be just north of Beantown.
For authenticity I’d prefer a dromedary, but I’m pretty sure showing up with any camel will blow the doors off of any lame swan dress.
Also, showing up with a camel likely shortens the time I’m welcome at the party (they’re not real good with using litter boxes) - another plus.
Otherwise I’d have asked if you fine people could point me to a swan dress in men’s size XL
What, are you kidding? I’m an Eisenhower baby. I remember cigarette commercials on TV!
In a pinch you could put a fake hump on a llama and say it’s a baby camel. 
A camel near Marlborough? If the OP weren’t a member, I would think this was a weird cigarette ad from a bot.
Years ago we were invited to a neighbor’s Halloween party. We didn’t really want to go, but they are neighbors, so… My gf purchased a headless horseman costume and I was a zombie. I walked, she rode, people ooohed and awed and we went home!!
There is a camel ranch down the road from me, but sadly for you it is on the west coast. No help.
Might be easier to find a Brough Superior. More fun and less mess, too!
