To keep you updated on my plans, the gym will remain open. I'm still working out the details on exactly how and it might involve a very small membership fee but it will only be what's needed to keep things running.
I am also considering setting up an area on the ranch where Pokemon can spend time, especially the ones that don't resemble any other animals here. That won't need much ongoing upkeep but I suppose someone could offer babysitting as a paid service if people wanted to be able to leave them there while they go to work. We bought the land here, it is not something that came through like people's houses, so even if I disappear someone will be able to take over the property. The gym as well.
