ZGZ - Boarder's Paradise.

The Zero Gravity Zone is a vast, multi-room indoor extreme sports experience in Ocean Shores, which appears in the stories The Big Day and After Shocked as well as the video game Zero Gravity Zone. Its street-level gate facility, which we saw from only one approach, covers only a very small area, hence most of it may be underground or buried in the side of a hill (at least one fan thinks it may have been built in a former Golem Enterprises facility).
