As far as access on Nance's Ferry, I once walked out into the field where the farmer was mowing and asked for permission to walk along his pasture and he said "nobody has ever asked, but thanks, and help yourself".
Now, rules of thumb. IF you see garbage along the access trail pack it out, and if there are more than one of you, walk single file as not to tear up the hay which is what they are trying to grow. Simple rules
I am a great admirer of spectator sports, especially on television; it keeps the riffraff off the trout streams.
