I track using my GPS watch. It's fun - I like to see the total miles, elevation gain, etc. It's a good safety backup - I mark key spots (saddle, etc.) that will enable me to backtrack/navigate if my inreach/phone goes down. It's also a useful tool. I'll send others the GPS track if I'm about to head back to the area to assist if I ever need SAR. I also upload the tracks to google earth so I can review over the offseason. I go back and mark each time I saw an elk, heard one bugle, etc. Over time, you can start to see the patterns emerge -- they tend to be in this sort of terrain, at these times, etc. That is fun, and can also help find new spots - just look for other areas with the same characteristics. I've also been surprised at some of the "micro-areas" that I've missed - looking at my tracks, I tend to do large loops and, even after hunting a general "spot" for years, there are still some specific areas that I've never ventured into. And, of course, it's a good way to relive the experiences -- "Oh yeah, that is where I missed that spike at 12 yards my first year of hunting because my bottom cam rested on some deadfall and I panicked."
