"Hi The Crest bus will now link with the YART service in Mammoth without the overnight stay. So You will be able to get on the Crest bus in Lone Pine and into Yosemite in one day, four days a week . This is a great service for the JMT hikers and many others traveling into the Sierra . Also the Southbound bus now takes you to the Train station in Lancaster 3 days a week , that gets you into LA the same day or links to the Greyhound at Mojave. Thanks Doug"
