Mistreated While Crossing the Border (Prt 1)

I was heading to TJ on Sunday, picking up my mom from the airport. I went with 3 of my friends who had nothing to do and decided to join me and my quest to come back alive from TJ. Along the way we realized that none of us had passport,but we did have our drivers license. Along the way we say many things that we didn't like. For example this sign

We thought we were going to see people crossing the freeway so i was driving extra slow around 80mph. We did see plenty of border patrol along the way, but we didn't see any immigrant crossing, and if they were crossing they were doing a good job, not that i approve or anything.
It was around 9:30ish when we crossed to Mexico, AT NIGHT!!!!, at the time we thought we were unstoppable. I was glad that i brought a couple of friends because you cant see anything after you cross the border, because there aren't any street lights. We were joking around not to be afraid of anything because we didn't want to end up like this :(
