I was daydreaming about using my airline miles to attend Camp New Harmoney, but this page:

https://www.sffmc.org/harmony_body.html

says that registration for Camp New Harmony for one or more days is full. There's a waiting list.

Apparently registration for 0 days is still open, but that would be a long way to travel.   :)

I'm happy that there is such enthusiastic response to the camp.
