Here in PA, we are allowed to "spot deer". That is, we go out at night, drive around with a 2 million candlepower spotlight and look for deer. As long as you don't have a weapon and stop at 11PM it's perfectly legal and pretty popular in the fall and winter across PA.
I've lived in some other states where it is strictly prohibited. When I lived in KS I asked the Dept. Wildlife and Parks if it was legal and they said, "there is no law that says you can't, but you'd better have permission off the landowner and be ready to answer some serious questions if an officer stops you."
Just wondered if "spottin' for deer" is legal or popular anywhere else.
