Thanks for all the replies. Sounds like we can't plan on good weather up there March. Too bad.
Now thinking of riding from Las Vegas and going south through Mojave Reserve, Joushua Tree park, check out the Salton Sea and head towards Yuma. Day 2 ride to Grand Canyon, day three ride back to las Vegas. Probably riding all tarmac, renting an RT or K1300GT.
Any thoughts on this would be appreciated too.
