Exurban, When you've got a good surface like this you can really haul ass. I'd find myself doin' 55 to 60mph and was lovin' it. The potholes and the mud will certainly slow you down. Then you'll find yourself just waitin' on construction. Our group had good weather during the entire ride so there wasn't much to do with mud and washouts that a big rain will bring. We did have to watch our following distance between riders because of the dust though. Have fun. It's a great ride.
