my brother is very good at falling asleep while he's hunting. he's also very, very good at waking up at the right moment...
couple years ago we were hunting together. we found a spot to sit and watch during the midday hours, while waiting for prime time... after he'd been asleep for a good 30 minutes or so, a buck wandered into view, maybe 50 yards or so off... i tried to wake him up, but couldn't, at least without scaring the buck off... hell w/ him, i think, i'm gonna shoot. so i got all lined up, and just started the trigger squeeze, and notice some movement to my left. yup, he had just woken up, and was plugging his ears. i tripped the switch, and we still laugh about that to this day.
i'll never admit it to him, but i really was hoping he'd stay asleep until i hit the switch... would've loved to have waken him up by lighting a fire!
