I empathize with your situation. I'm in the same boat. Even with hundreds of subscribers, if everyone's lurking then the community gets stale and withers. Becoming a one-person content machine isn't sustainable.
Though on a brighter note, with this post you just gained a subscriber to your community. Browsing through it reminded me of how fun geocaching was. I just dusted off my old geocaching.com account from a decade ago. I'll have to take my kids out and see what we can find!
Spoiler alert: the drain is just a straight pipe to a bucket below the counter.
