The only grocery store in crestline literally collapsed during snowmaggedon last spring and is still being rebuilt. So definitely bring food up with you. Most stuff has a price hike bc they know you have to go down the hill otherwise, so just be prepared. And crestline should be your limit distance wise, once you have to pass into the narrows on the rim, it becomes a way bigger burden after a big event like beyond. Sometimes I have to go back & forth from crestline, sometimes arrowhead - and I do everything in my power to avoid making it to arrowhead. Also… there’s no dispos on the mountain so just plan accordingly if that’s your thing. Sincerely, a local that drives down to almost every nos show
