I've lived most of my life in the northeastern USA so I found the desert east of San Diego fascinating. Unfortunately we didn't have time for many stops so I took photos out the window of the car for most of our day trip. Next trip I plan to take my time. Most likely I'll go with one other person who also likes to take lots and lots of photos so we may be gone for days or weeks.
