Sounds to me like you knwo the difference. The guys from PA were just stating how according to certain regs it is illegal to do either form of that with a vehicle in PA. Sitting in a blind or a stand can be sparked by a vehicles use. Take example you are out checkin trail cams or whatever on a 4 wheeler and you see a big buck chasing a doe not very far away and heads into a thicket you know of. You were not even planning on hunting there that day but you rush home grab your stuff and climb in the nearest stand to it. An hour later that buck comes by and you shoot him. The only reason you got him was because you were out riding your 4 wheeler around looking for deer sign or whatever and saw him. I don't know how many times I've been on my way to deer or turkey hunt and saw them in places I never would have gone that day but do because thats where the game wants to be at that time. According to certain PA regs that would be illegal I guess but only as an interpretation of the law and not exactly how it reads. WCL
