X-Hobby was running the Chibana track. However, I think they lost interest and that may be why Siro is running GP at Ryukyu Mura now. The combo lock was taken off about a year ago (combo was 2006). Last time I was out there you could get in from the side gate next to the restrooms. There was an outlet on the outside of the restroom that we use to plug into.
Jason....are you back on the island?
Does anyone have any more word on RCP?
