Palomar Observatory is a great drive:)
Its within reach and a m/c mecca road(up the Palomar mountain) there and back. I know you're driving, but still a nice road trip, a few hours total time if you're in a hurry. Most of the day otherwise. South from Santa Ana a little ways to 78 East, through some nice CA. country. Temecula Old Town has some nice places and Julian is another cool town in the mountains, all around Palomar. Research your map and best regards to you and your wife. You won't forget this drive, if you take it, Happy Trails, Randy:thumb:usa
