Although you can't go wrong by just wearing a bit of hunter orange, you really need to be mostly concerned with MFA Deer season IMO.
Elk isn't really in the woods so much and are hunted later in the year so you usually see track in snow as well as have some clear lines of sight. Confusing the sounds of a bear with that of a human is very difficult, but not impossible, to do. Birders usually hunt with dogs and unless you smell like a bitch in heat you won't be what that dog points at.
Snaffle season, on the other hand, is something I didn't consider. What ever happened to the good old days of Carl Spackler? What have we come to?
