I am in the same boat hunting public land. Where I hunt there is no real "untouched" areas that bucks can hide. Only the ridge where the deer bed which is of course private and off limits. I was however able to get a buck 11/28/08 nearly a week and a half into gun season. He walked off the ridge around 15-30 minutes before last light. I was guessing I would get lucky at the LAST possible point a deer could go in their corridor and catch one stepping out for the evening or rushing to the bedding area at the last minute before light. It paid off.....good luck....
