My husband & I are heading west on Interstate 10 mid April (18th)in our camping trailer with our small dog. My husband has never seen the West Coast & I haven't been there since I was a kid. We have 3 months to travel and need to be back home mid July (15th). Tentative plans are to stay on 10 until Tuscan and then head up to the Grand Canyon, Las Vegas (we have friends there) & then over to California. We have friends outside of LA & also San Jose.... Up the coast to Whydbe Island, Washington & then we have friends outside of Butte, Montana. I don't want to be on a strict itenary & we'll evaluate our time left when we get there. That being said, we have no idea what is a must see or great routes to take with a camper. I am interested in showing my husband the wonders of the states & what REAL mountains look like! Any suggestions would be appreciated.
