Couple pictures of my attached garage when I was using it as my race shop.
It wasn't insulated so often it was colder in the garage than it was outside, basically just a spot to get out of the wind.
The following winter the landlord gave us a small budget and we insulated the garage and put up OSB on the walls.
Made working on the sleds much more comfortable.
Pulled the rope on my sled after putting it together and didn't expect it to fire up right away, filled the garage with the best smell in the world, 2 stroke smoke!
