Preparing for the big trip. How much stuff can I get into the top carrier? How much stuff can I get into the truck bed? ...apparently a lot. Wednesday June 10, we hit the road.... First stop, Casper, Wyoming. Dinner at The Hangar. Sibley Lake Campground in Bighorn National Forest. Awesome place. Sibley Lake. A couple locals at the start of our hike around Sibley lake. Bighorn National Forest. Bucking Mule Falls hike. Bighorn is a National Forest not a National Park so I can fly my drone. Beautiful canyon and falls. Yellowstone North Entrance.
