a colleague of mine at work really wanted to go hunting last year...i set him up in my stand on public land and told him to make sure he cleaned up any trash he had (sandwich wrappers, whatever) his response "it is public land, let the state clean it up"
needless to say, i removed him from the stand and told him he will never hunt with me again
really sad, i know when i go fly fishing for trout, i always take a creel, not to keep fish, but to carry trash out
