Hi Ya all. I am planning on taking a cross-country road trip from Ma to California. We plan on staying in San Diego for a few days. I was wondering how difficult it would be if we decided to go to mexico for a day. What is Baja California like and what can we expect for delays, waits, customs, and all the other stuff. Do you think it is a stupid idea? If we just planned on going to into Baja California for a quick visit would we need passports? Please Help me!!!
