Smoking in the Garage

[dwoodward]

I just pictured this all in my head btw, i have no problems sitting outside for a cigar if I can get out of the wind lol.

Most garages have a window. Just use your fan idea and open the window a crack, and you should have a decent draft moving thru the garage, it might be a little chilly, but should be enough to keep the air moving out. The key would be sitting near the draft but not in it, so you are warm, but when you exhale, the smoke moves towards the moving air because it's lower pressure, it should (according to physics) get slowly pushed out thru the fan.
