September through May is all good scouting season here. As I primarily hunt November, the closer to that, the better. The farther removed, the blurrier the picture the sign leaves behind. Thus, my go-to spots, I try to scout closer to the end of season. By March/April, I'm usually onto fishing and once inawhile taking a jaunt through some new territory. I hate being in the woods June-August.
Pre and inseason scouting, I'm careful. I don't really go into bedding, I stick to perimeters, a lot more macro with deductive reasoning.
Post-season scouting, I flip the script and try to focus on picking a smaller area apart.
Snow is tricky. None is pefectly fine, a wee little is wonderful, more than a couple inches is pretty much useless and potentially even counterproductive as deer will do weird things in winter and leave hella sign in places that are meaningless without snow.
