We drove from Driggs back through the parks, stopping to let our brakes cool after the trip over the Teton Pass. In Grand Teton we went to the most amazing visitors' center ever, at Moose Junction. There are moving videos on the floor! The kids loved touching the animal furs, and proclaimed the lynx the softest, and the bison softer than they expected. In Yellowstone we visited the Mud Volcano, which we'd skipped the prior day. It got late really fast - how does that happen? - and we thought we'd be driving in the dark.
