I am not sure how the county jurisdiction works, I believe in Texas they keep much of the power at the local level but I would have to really look into that. My knowledge is going off the state and local government test I took for college credit 10 years ago. I know of one farm to market road locally that recently outlawed bikes, I believe they felt it was too dangerous given the road and the urban sprawl engulfing the city. We also have a toll road they made it illegal, the toll road is part of US 183 but other parts of 183 it is legal to ride, in those parts it is not a freeway but more like what Hwy 287 looks like. I still believe it is a police department with someone complaining that likely has a lot of pull or money. Seems like a waste of time and money to be locking this guy up not to mention the court costs.
