if you are in the country for less than 7 days, you do not need a tourist card from immigration. By all means bring doc's to re enter the USA. I
always get the tourist card, just so if some crap happens, I am legit, but I also travel down quite a bit between Oct and June. Try the east border
crossing at mexicali on the way back, last week we were the 3rd car in line ( sentri ) but the ready lanes were looking pretty good, it's also a very
easy enrty, although there was a little bit of construction at the specific turnoff to enter |
