It's kind of tacky, but this place sticks some of the antiques OUTSIDE for display. If these are so valuable (and they're priced that way), why are they sititng them out in the weather?
Anyway, I've found that 90% of their stuff is junk, but every once in a while you come across a real gem of a find. Like a china cabinet that looks like it just came off the boat from victorian england...
Be prepared to make several trips there before you find that gem, but it's worth the drive!
