The few game wardens I have met have been nice enough. But then again, they should be since they are violating your constitutional right against unlawful search.
My uncle was fishing one time with my aunt. A game warden was up on the bank watching him and my uncle didn't know he was there. He handed the pole to my aunt while he dug something out of the tackle box. The warden wrote my aunt a ticket for fishing without a license. There is no room for common sense anymore. Their motto seems to be "Find em, bust em, get the money out of em".
