I will start off this little story with full disclosure...I am spoiled to live and hunt where I do. I know this. There, I said it. I moved here because my wife was from here and thought "please don't throw me into the briarpatch" when she suggested we move back to her home county.
I train every summer for the chance to jump start my season with a hunt for mulies or elk out west. I run, bike and swim, train for a couple of sprint triathlons, and use my mountain bike for summer scouting. I cover about 10 miles a week on my fat tires and another 50 or so on my skinny ones. Here's the machines:
The great thing about traveling roads like these on my fat tires is that deer don't hear you coming. I can park my truck near an area I want to glass, ride my mountain bike in and get pretty ok pics and never really spook the deer.
I try to end up near my truck or home as darkness nears and more than once I have ended up with a eye or mouth full of bugs while trying to pedal back home with my headlamp on.
Sometimes this is all I get of a good buck. Ears, horns, etc but enough to know that a good one is there in July. What I have found is that if food is around in October (our opener is the 1st) then the bucks I glassed in July will be within a half mile of where they were. If food is not there I look for the nearest late green soybeans or fresh cut alfalfa or clover.
