I'll have the rental car while the family is at Legoland. I assume I'll have at least six hours of freedom and I plan on going east to Anza-Borrego for a hike.
For the return drive, how much consideration can I give to going east to CA 86 and returning to San Diego on I-8 if I'm doing this on a weekday?

On the other side of the border, I want to take my 2nd-grade daughter to Mexico for a day. I haven't been to Tijuana in 25 years. Thoughts on walking over the border and using that as a cultural experience, vs. renting a car there & driving to Ensenada, vs. driving to Tecate and just walking around there?
