Bam,
Obviously, here in Ohio, I fish more ponds (private) than running water, but the same applies. I pick stuff up, help carry groceries, have given folding chairs, rods/reels, tackle & instruction to kids. To me it's just a small payback for the property owners kindness & trust. About twice a year, I'll keep some bluegill for eating, & I always split the filets with the property owner. I also make sure I have plenty of cold beverages & munchies in the Jeep in case they join me.
With all the vandalism & trashing that goes on nowadays, a trusting landowner is becoming a rare comodity...one which is to be treasured & appreciated. Good post.
Mike
