You gotta wonder about weigh stations. We were coming back from an event at Pikes Peak and cut down through New Mexico to I-40 and out to AZ. Coming into NM, they weighed the truck/trailer combo I was driving and I was below a certain weight by a couple hundred pounds so we didn't have to pay any additional fees. On the way out they weighed us again, and this time I was OVER by 400lbs - interesting that I somehow gained about 600lbs going through the state, even though we didn't even take on fuel! Of course the major PITA was that I was in the last truck and since we all thought our weights were fine, all the others had already exited the station and were on the road. They had to send someone back to the station with the checkbook to pay my fees.
