I was surprised by how few HazMat restrictions there really are around the country. I check the registry and my RM 740 does a pretty good job of routing me. It's a 100 times more likely to wanr me away from a non-existant HazMat restriction than to forget to tell be about a HM restriction. I can't remember one restriction it didn't tell me about. I'll probably be retired before it stops telling me about the phantom HM restriction on Atlanta's I-285. There isn't a restriction, but Rand McNally is waiting for the planets to align before they ever fix this error.
