Before riding in the Tour de Wyoming last summer, I thought I knew all I needed to know about cattle guards. I grew up in Missouri, and on hunting trips out in the country around my hometown of Independence (a K.C. suburb) I had seen plenty of cattle guards at the end of long farmhouse driveways. Before that ride, I also thought I knew all I needed to know about tar snakes. I'd ridden on a few roads up in the mountains of north Georgia that feature the dreaded chip seal, which is bad enough, and asphalt roads that have some small cracks filled in with tar. I was wrong on both counts.
