I will be in San Diego (north county) for the next 45 days (mid july-end of aug). I love day trips and beautiful scenery. Has anyone done road trips and/or is from the area and can suggest some places to see?

I love dramatic landscapes, small towns, beautiful farm lands, funky buildings and great small bars. I have a touristy book about San Diego but am looking for some things a little bit less touristy.

I would even be up for a Mexico trip- but probably not Tiajuana. More beachy type, i guess baja, stuff.

Thanks!
