Group discussion on all things related to owning, maintaining, and yes, enjoying that Spa/Hot Tub. Start a group and invite friends and neigbors to join your group. Share stories on throwing ice into the Hot Tub during the summer to make it a "Cold Tub," or hot-tubbing in the winter with snow coming down and your enjoying some jet action in your 95 degree spa. Start a group, let others know how you opened it up, when/if you close it up, and how many people you fit in it at one time. Skimmer is the limit, start a group, join another, the point is community participation.
