Not that it's Maine specific, but Ocean State Job Lot is a weird f-ing place, too. I actually love it, and was in there the other day opining to my wife that were the zombie apocalypse to go down, OSJL would be a solid place to hole up, if you could get some barricades in front of the big sliding glass doors.

I just bought some shampoo there for dirt cheap and when I got home realized all the copy on the bottle was in Czech ;)
