Well, maybe not a castle....but a shack!!!
Here's mine. A 16x20 carport with a 10x12 shed in the back. Dirt has been recently carpeted
...keeps the dust down. Ain't much, but it is the best I have ever had. Future plans for a concrete floor. The Road King hasn't complained at all. Maybe she likes it.
Because it is my bike and I like it that way!
