Ryan, I know where you are coming from. Sadly I didn't even complete my daughters HS graduation gift. Lucky for me she won't need it until she starts college so I still have a few weeks :(. My biggest challenge isn't a messy shop, but the exact opposite. I work out of a 2-car attached garage that is the main entrance into our home. I HAVE to clean up any mess I make that day, which makes me not want to make messes most days. The other challenge I have is I have too much equipment. Yes, i's true :) In order for me to do anything I end up moving stuff around which takes lots of effort on my part. And since all this requires my garage door to be open, if the weather is bad its not an option.
