There was one hunter that was camping with his truck next to his tent. The elk tried to walk between the tent and the truck and stepped on him. That was during the rut when they were running all over, though.
One of the places I go is right next to a national park campsite. In the mornings the elk will leave the park and go up the hill/mountain and leave the park, in the evenings they come back to the campsites and hang around people. Strange animals sometimes.
I've had blacktails that have hidden within 100 yds of camp (chopping, fires, some shooting), and stayed there for days. Find their beds, trails, scat--eventually them.
