Oh! And the Churros are good but the ones in Cuba were better (lo Siento mi Mexicano amigos)!
If you choose to go to Mexico (via the border), here are a few things I’d recommend.
1. Take into consideration your time. While going into Mexico was rather quick, coming back took way longer (I was in stop and go traffic for 3+ hours!!!)
2. Be prepared to deal with pushy sales people at the border crossing. It’s cool for like 30 minutes but after 2 hours it can get annoying.
3. Watch how you spend money! For example, signs will list a soda for $48…but the price is actually 48 pesos.
4. Border patrol doesn’t play! Have your proper Identification (passport etc.) available and don’t try sneaking anything back in.
5. Ask around and get the opinion of locals before galavanting off anywhere.
6. Know a bit of Spanish, it’ll get you far (see the post on Havana for more on that).
7. If you choose to rent, PLEASE read over your terms and conditions and check with your rental company to ensure that you are covered to go into Mexico.
An Alternative: Go on a walking tour. Certain places in San Diego offer walking day-tours to and from Tijuana.
