I forget I'm carrying hobby tools until I get off the cab and then I go damn I have to throw them away. Everything happens so fast on the way back. I'm in La Coahuila and before I know it I'm at the border. I hate to throw the condoms and other hobby paraphernalia but yup I don't feel comfortable carrying them.
One time my buddy bought a big sombrero and he was wearing it the whole time even while crossing back and the border patrol asked him if was bringing something from Mexico and he said no. I thought it was pretty funny.
BTW I have always wanted to buy a wrestling mask on my way back but I always forget. They are cool masks. IMO the best mask is between Fishman, Canek, or Dr. Wagner.
