Derek, I was keeping up with this, in the beginning and then the situation with my Dad kinda took precedence. Any way, I've managed to get some time this evening and went through the whole thing and, buddy, I have to say that you've got one Mighty Fine Man/Bike Cave there.
You have every right to be proud.
Enjoy, you've earned the right.
BTW, if you don't keep an eye on Sam, he'll convince yu that he needs to move in so he can be there to properly set up and maintain a garden.
Take care, Bill
