Never wear outdoor shoes in the room, I slip on a pair of sandals that are inside the room by the door.
Thanks snow!

That info really helps... Where I'll conduct my CO2 injection is in my mother cabinet... it's 12"x24" with a 24" height... so I won't walk into it... trust me.

But thanks man... that's in my To Do list... CO2 killings
