After reading this thread, I find that somewhere thru the years, I have made about 90% of the previously mentioned mistakes.....sometimes more than once. Hahahahaha
I'll add a couple....
The afternoon before heading out for a day of hunting, DO check all automotive fluids; check the air in every tire (including spare); and top off the fuel tank.
DON'T buy a new toolbox for the bed of your pickup, then NOT put anything in it (tool-wise) before you go hunting next.
If you have an empty toolbox, and you leave your wrenches/sockets/screwdrivers/hammer at home...don't complain when you break down 50 miles from home & need a tool.
DO remember to keep a tow rope, chain, or come-along (or all 3) in aforementioned toolbox, even if it hasn't rained of snowed in weeks.
Trust me....if you sometimes think that your 2wd truck is a 4x4....it IS possible to get stuck on a road that is marked "unimproved/travel at your own risk".
DO also remember to take a shovel, or other digging tool. You just never know.
DO remember to keep your inhaler in your pocket, if you are an asthmatic.
Leaving it in the truck proves nothing when you are having an attack 1/4 mile from the truck & the inhaler is in the glovebox.
While "on stand", DON'T be thinking about the next stand location. Keep you mind on the one you are currently calling.
I can't count the number of times that after 20 minutes of seeing nothing, my mind drifted to deciding where to go next. Only to snap back into reality, and realize there's a coyote staring at me from 100 yards away....and I had know idea how long he'd been there.
If you even THINK that you might need to pee before walking away from the truck, DO so.
DON'T wait, and then 5 minutes into the stand, decide that the cup of coffee (or in my case, a cup of water) that you drank earlier, has an immediate need to be relieved from your bladder.
