While visiting my grandma this Mother's Day, I asked her if she'd ever been to Canyonlands. (I'm camping there soon.) She said her and my grandpa used to go down there four-wheeling when it was still allowed.
People used to try to block them on the main road by driving down the middle. She'd wait until there was gap and speed past dusting them.
The picture was taking a few years ago when at eighty, she still went for a several hour family ride.
