That realy stinks that they have to take it that far for an incidental trespassing. That would realy burn my hide. I wish you luck with talking to the judge or district attorney. Like you said it would be a shame to have criminal trespassing on your record. Maybe try to find some web sites that talk about the various trespassing laws for your area or since the game wardens where nice, try talking to them and see if they have any thoughts.

Hunting is really a beutiful thing, I hope it does not turn you away from hunting.

Good Luck and keep us posted.
