I was driving from TX to AZ, and passed through NM. There was a Border Patrol checking station on the highway and all the vehicles had to go through it. Well, I thought they just waved the vehicles through so I didn't really stop. Mistake. A Border Patrol agent called out to me, and eyed me suspiciously. "Why didn't you stop? Didn't you see the stop sign?" Honestly, I didn't as the vehicle in front of me was a big truck that blocked my view. That's what I told him. He then started to ask me a bunch of questions about where I came from, where I was going, was this my personal car, etc. Then, he shined a light into my backseat and looks to see what I had in there. Finally, he waved me through. What he didn't find, was a Mossberg 590 shotgun, and a duffle bag filled with about ten handguns that I brought on the trip for range shooting when I got to AZ. That would've been a little hard to explain.
