Today I ran an add on Craigslist offering to take anyone's free wood. I already have three takers. Should I be worried about going on to someone else's land and taking trees, even though I obviously have their permission? I live in a small town so I don't think this is an issue, but I used to live in Chicago and there no one would even think about doing this because of the possibility of being sued if something happened. Thoughts? Experiences?
