So I took one of the dogs and spent the weekend camping/scouting at one of my remote hunting spots. I took the mountain bike along and spent some time riding along the two tracks around the area with the dog. This definitely has potential to cut down on the time and effort to get to some of my spots. Even in the 85 deg weather I stayed cooler on the bike than I did during the time I was just walking around. I will say though, riding the bike brings a whole new meaning to the term "saddle shape".
On a more serious note, what pressure are you mountain bike users putting in your tires? I know there's a balance between easy pedaling (higher pressure) and control in sandy areas (lower pressure).
