Do you have one?
I have a SENTRI pass. If you have a passport and no arrest record you can get one too. Google GOES (global online enrollment system) and apply on line. You will have to go in for an interview. I cross the border at San Diego. Without the SENTRI pass the wait time is 2-3 hours on most days for pedestrians and cars. I walk back and my wait time is about 5 minutes or less. I would never go there without the SENTRI pass. You can use it at the airport too.
