At first I kept EVERYTHING....then when the amount of plain bottles became insane I went through them and have gotten rid of 200+ to the salvation army or others like it. I now keep the real neat shaped bottles, real small bottles or the embossed bottles. I leave the rest there.
yeah, I liked this thread. If it's a privy, I rebury the common bottles, if it's a dump, I leave them up against a tree or something for someone to find after me. I never break bottles on purpose, totally out of superstition. Those bottle gods are sensitive you know. If they see ya bustin up bottles, you can wind up on a dry streak that may never end!
