Yep, Ill go along with Harris Ranch, Just follow I5 North. I also forgot Catalina Island but watch out on the approach. Also if you just want to have some fun practicing take offs and landings go to San Bernadino. If your good you can get 3 take offs and landings in one length of the Runway!
There is a Jepsen Book which has all airports in for the US South West. It has all flt information inside (Rwy lenth, taxiway map, frequencies etc) and local attractions, hotels etc situated around the airport. Suggest you buy it. You can pick one up from Aircraft Spruce, Aviaiton Supplies, Great stuff at Great prices. Fly to Corona Municipal (wave as you pass over my Condo) and call them as they have a shuttle service from the Corona airport.
