I think that US customs needs to get their act together and go to a simple system that would use technology better, not to make four changes in three years.
What happened to FAST? I got nailed for $250 this year for the transponder and I have no way to look at the balance for the transponder or see if I even get charged. the last time I was in the van, I still had to pay to cross, which the transponder was supposed to cover per the US customs people.
