You need some decent wind (+4m/s) from the West for thermals to be usable. Surprisingly flyable even in strong winds (+8m/s).
access
You can leave your car on the paved road and then hike for 30 minutes. Driving to the takeoff is possible with a high clearance car if it hasn't rained significantly (the mud is very sticky).
regulation
In class G airspace, but during the week there's usually a military NOTAM on the edge.
