you know I would have loved to do something like that cause I want to help
the police keep the drugs and criminals from crossing the border especially
when there aren't just drugs, like explosives or something. But at the
moment I'm learning electronics which is proving to be extremely difficult.
If you guys still need some help six months from now don't hesitate to send
me an email because I may be more able to help then.
How expensive are the sensors anyway? Just curious cause I usually am
extremely surprised at how expensive the simplest things that the government
decides to do are.
