A quick Memorial Day weekend, plus one day, to visit Great Basin to see the Bristlecone Pines at 10,000 foot elevation, and a 90 minute tour through Lehman Caves. Then on to Moab, Utah to visit with my son and his girlfriend. He is working as a guide doing 4x4 trips into Canyonland National Park, and guiding whitewater rafting trips on the Colorado river as well. While in Moab, we also visited Arches National Park.
