+1 on drywalled garage for my homes, one is attached, the other not.
The slatwall looks appealing. I did not know about that, but will look into that when I re-organize my garages, which may be the next projects.
So many things to do, I don't know how people could ask ER's "What ya do all day?". Between travel, hobbies, home projects, I do not have enough time (nor energy!).
