I found no clubs of any kind. Houston had one, but it is no longer active.
However, if you’re in the Tomball or surrounding area I did find a park that would be a great place to ride a unicycle. Especially a Muni. It is called Spring Creek Park. Located on 15012 Brown Rd, Tomball, TX 77377.
Try posting in some local group, peotentially make an FB group for your area too? If no clubs exists why not start one?
Oh, I could never do that. I would need to learn how to ride first. Meanwhile, I am well known all over town, and the neighboring towns, and not in a good way. I am extremely hated here, and for good reasons. If they found out I was involved in the group in any way. Nobody would ever come to it.
I only posted this in case any first time unicyclist in this are came looking for a place to ride. It is a very small town. Finding a place to ride even can be difficult.
