How did I miss this? You sound exactly like my dad. That is by far the best way to live. If I ever make it to that age I plan on having the exact same mindset. You can't really get old if you're always a child. Keeps life interesting that way too.
Bugs, It might be a good idea to get your 20 yrs in the Army and then become a wildlife biologist. Collect 2 retirements.
And I might add that having military experience gives you a huge leg up in applying for federal jobs. You get what are called preference points and are therefore shifted to the top of the list pretty quickly, given that you have the same degrees as everyone else. Most of the federal agencies employ wildlife biologists... NPS, USGS, USFS etc and also ones you wouldn't normally think of such as the DOD. The Department of Defense might also be an awesome choice for someone that is coming out of the military anyways. And two retirements doesn't sound that bad either I guess.
I have a system I use in Whitetail hunting during the rut that seems to work for me. When I make a mock scrape in the area I wish to hunt I will place a couple of 35mm
film canisters (film removed of course) in the scrape after I have cleared out all leaves and other debris. The film canisters are filled with cotton balls and saturated with doe in heat urine. This keeps the urine from soaking in the ground and can be refreshed on each trip if needed. I will also use the tarsal gland of the buck...
