I used to ride out here, had to check in at the Twin Hills store across from the park entrance. The facebook page has gone silent. The phone number provided, 940 683 4959, which I will assume is the landline phone at the store, just rings and rings.
I wanted to drag the family out there for camping this weekend.

I went by Twin Hills store this morning and it appears to be closed, however there were signs directing those interested in the cycle park to call Carol @ 940-393-6658. Mr. Bilby who owns the land and the store has been in declining health for several years.
