Very cool man. I'm lucky enough that when I set mine up, I'm going to vent mine outside. I've read a lot about the air shifts due to the draw and whatnot but winters are never a problem for me, I live in the southwest so I don't need to heat my shop. Cooling, now that's a different story. I tend to work in the evenings moreso than the day in the summers, so I'm good with venting to my side yard.
