So sorry to hear this!
While I can’t go (the corns not planted yet) I have been following along and would love to do it sometime. This is a totally cool thing that you have had the vision for, you have built, and you have followed through on and hopefully things will work out so you can go. So sorry for your loss that you know is coming. I hope you can have some good final days with your mom, I know I did with my dad and that is a good memory.
As an aside, I would offer support in terms of a shop and/or camping if an emergency arises, I am between Sheridan and Lebanon.
Your in my thoughts and prayers.
