I tell you something, these rattlesnake dens fucking stink. The smell can be so strong that you’ll smell them before hearing the first rattle. The urine and feces sits over winter and ferments and when that snow is gone and these little shits start moving about, it woofs that stink in the air.
Truck is there like ten yards away with the door open. My truck would be 1/4 mile at least and sealed up like a drum, and I'd be covered head to toe in three or four thick leather animal hides, and maybe then I'd be brave enough to fly my drone over. No way I'd walk over the with a cam on a stick like this guy.
