Any colored box indicates that the particular resource (i.e. tunnel, cage, or instructor) you are viewing IS NOT AVAILABLE at that time. A gray box indicates that the particular resource IS AVAILABLE at that time.
IMPORTANT: Facility availability changes continously. This tool only allows you to see what resources have not been scheduled "in advance". Walk-in traffic will reduce the actual availability of tunnel/cage space. After checking availability it is RECOMMENDED that you call ahead to reserve your space (credit card may be required during high demand periods) to ensure that it is there when you arrive.
