Cali, Here we Come!

D and I have been planning our trip to California/Las Vegas. So far, we have planned to stay the night in the Sequoia National Forest, take a helicopter tour of the Grand Canyon, and go whale watching in Monterrey. I am so excited! If anyone has any suggestions on good places to go or great things to see and do in Cali, let me know. I think we're going to drive down the scenic coastal highway, but I'm not sure what there is to see and do.
