I'm not sure where Chula Vista is, or if that's even where you'll be caching.
Look at my profile (Sean's Mom). I do almost all of my GeoCaching with my 9 month old son. So, if you're in the Chino/Montclair/Upland/Ontario areas or near Visalia, there are a few on my list that would work for you.
Thanks for the info, guess I should be more specific. The San Diego area is where I am looking.
