Looking to fly in to San Diego and drive up the coast to Portland, OR, then take the train home to MKE, stopping at Glacier Lake Natl Park. Need to figure out how much time we will need to see any "must see's". I have already been to San Francisco so really don't need much time there. Not much interest in the LA hoopla, so might spend limited time there. Would like to see Joshua Tree, Yosemite, Crater Lake, Cape Perpetua. Thinking about retiring to Oregon coast so would like to do as much driving there to check it out. Probably mid-May. Any suggestions?
