My work shop conditions are......
I live in it!
I'm retired and the wife won't let me smoke in the house so, I moved.
I sleep, eat and use the restroom in the house but other than that, I'M IN THE SHOP!
I have my 'puter, TV, heat and air, beer box, desk, and all of my tools within six steps of me at all times.
The shop is 14' x 20' with 9' celings. I have 3 windows, two outside walk doors and an overhead garage door. I open up around 7:00 AM and I work when I want to and, visit with friends when they drop by around "Beer-thirty".
I usually call it a day around 9:30 and go in to watch "Everybody Loves Ramond" and the 10:00 news and try to stay awake for "Jay Leno" until 11:30 or so.
Yes, I AM AS HAPPY AS A CLAM!
