Take a ride out to the Hotel Del Coronado. Beautiful old victorian hotel with a bunch of history.
Drive leasurely up (or down) the coast through all the cool little communities and take time to stop and check out all the local art. Some incredible stuff can be found.
Eat like a pig cause the seafood is so freakin good!
Then drive up to San Marcos and say hello to my aunt and uncle for me.

I can't wait for my next trip out west. That whole area is great!
