Great Post Arnold!
Welcome to my “paradise”. My happy place is a 13’ x 19’ train room with a 6’ x 13’ shop area accessed through the door adjacent to the mountain. This room is in the lower level of our town home. My wife does not like it when I call it the basement. It's a walkout so I guess it technically is not a basement. We moved in eight years ago and I started from scratch in January of 2014. I know that we all would die for more real estate, but I am happy with the space even though it can get a little crowded when I entertain visitors. In reality, it is "my world"; a collection of childhood memories and it functions just fine for me! When I am there, I'm magically 15 years old again even though I'm in an 80 year old outfit.
My pictorial tour:
Cheers, Dave
