ETA: My brother said Julian is still doing all the road side stands...there's even more now...pie houses, pumpkin houses...it's a twisty road - but it's well worth the drive!

Not free things to do...
San Diego Zoo.
Sea World.
W. Animal Park - now called Safari Park - in Escondido.
These are FREE...just the gas to get there...
The beaches are DEVINE!! La Jolla Cove or beach is great...Torrey Pines...
Then there's Coranado...Seaport Village ...Mission Bay park (we used to have MANY BBQs there when I was a kid!! Hopefully, it's still as beautiful now as it was then!)
Oh my word...if you drive away from San Diego - there's a place called Julian...it's up in the mountains - it's fall and they have stands of Hot Apple Cider, pumpkins, squash, and so much more...at least they did when I lived in San Diego years ago...my brother lives in Escondido. I'll call him and ask...
