Hello, on May 12 I'd like to start a trip from Las Vegas to Death Valley, then up to Sequoia/Kings Canyon Park, and then to Yosemitie... I have 4 or 5 days for the trip. Am concerned about late spring road conditions. I don't know the area at all. Wondering how many stops to make and where (the usual :-) Would be so grateful for any advice! Thank you, David
