How do you find bottle dumps?

I agree that under houses can be great..some of the really old homes have just a crawlspace. Alot of guys on the bottle forums I go to get to dig those. Basically belly digging, but they find some good stuff.

CkJeep84 hit it right on the head too. Construction sites can be a huge goldmine. If you have friends who work demo or construction, let them know you want some bottles. Some companies will just toss them aside for you so you can go pull them out of the pile. Most of the time they'll just hand them to you. I haven't heard of anyone being charged for bottles a crew pulled out/found. Nice to have a backhoe dig them for you.

The horse and buggy with horse bones next to it is creepy as heck! maybe the occupants got ambushed and abducted
