Folks, if you've recently upgraded or renewed your annual club membership but it's still not active, please reach out to the BOD or a moderator. The PayPal system has a slight bug which it doesn't allow it to activate the account on it's own.
I just went back, there are some pics of the basement in its heyday on the third page of this thread. There is also visio drawing on page 1 that shows the detail of the system (minus the frag tank that was added after it was created).
