Hello, I am new to this board and I have a question about driving on I-80. The last time I drove on I-80 was going to Wisconsin from Las Vegas. Well in Nebraska, there was a certain section of I-80 where a sign was posted saying something of the sorts, "Drug Sniffing Dogs ahead." It was something on those lines, but I got off the interstate pretty much right away and took some county roads around this area that was coming up. What is this? Is it a random pull over drug check? Is it a stop coming up checking for drugs? The reason I ask is because I am traveling out west to Colorado from Chicago and I am just curious to know what do I need to be on the look out for on I-80. I mean I am only going to have a small stash for myself. Nothing out of hand.
