I've been walking but I believe I will be using an ATV or snowmobile this year. I posted this last year - its how I did it previously.
My furtherest walk was 1 mile each way previously - state land. I will be using roads and private land mixed in this year. An ATV will be easy. I was more interested in a snowmobile setup if anyone has done it.
If you come to the end of a path, do not turn back, continue on and make your own trail.
I either drive my truck or ATV. I try not to walk much for several reasons. One for scent control, not the tracks, its the scent you leave behind. Always walk past your set. If you stop, they will. Keep moving. Speed of a vehicle is a big one. Canines can be few and far in the winter. Better to cover a lot of ground. You can make trails to your sets with vehicles. They will follow them. I like woods trapping the winter. Lease roads that are plowed are easy to access and dug up dirt to make sets against and on. Many days I have to redo sets to keep them working, so I don't like to check with field glasses. Good trapping! Animal
