Super Chronic: Seems like kind of a cool hobby to collect those. But I wouldn't expect there to be much of an audience for that museum.

This article was making me wonder what a museum actually costs. I do a lot of road trips and see advertisements for all sorts of weird roadside attractions.

So you'd need to rent or buy some retail space - enough to put your collection on display and preserve it. You'd need knowledge of what you have, so you can put it on the placards. People who visit your museum are going to want to know more about what you have, and you need to be the expert in it. A little marketing would be nice, so print up some brochures for hotel lobbies and rest stop racks. And every once in a while you're going to want to bring in new exhibits.

I've seen some that have hours either "by appointment only" or Friday through Sunday, 12-6 - obviously being run as a hobby or in a private residence. (There's a baseball museum in Massachusetts, I think, that's run out of someone's house.) I can't imagine that they make money, but if you have the income to take the hit, well, lots of hobbies are expensive. Maybe you can write a book about your interest and sell it at the venue.

This is all just spitballing, of course. I've never been interested enough in anything to collect 500 of it and put it on display. But this is what I'd imagine someone would need.
