I met John and his wife Joan years ago when they visited Washington State for a presentation. He signed one of his books for me. He was pleasant to talk to. One of the areas that we talked about was cat tracks in snow. Bobcat, Lynx and cougar in the ways of paws, straddle, stride and tail dragging. We talked about track following with cross country skiis and snowshoes. Cross country skiis being faster on suitable terrain. Both methods are relatively quiet. If you can walk, you can use snowshoes.
Cost of ownership of snow machines is high. They make a lot of noise.
Time will tell. How do you feel when someone or something is following you?
I will post again: Sasquatch find you, you do not find them.
Western Washington has wet sloppy snow. If conditions are not correct, animal tracks can be obscurred quickly. A track / way would have to be pounced upon quickly ( no cat pun intended ).
