I made it inside once at my brothers house.
Fucking fumes were bad.
So he goes into his office and brings out his Quadra Breeze Ionic Air Cleaner.
Thank GOD I saw him as he was reaching to plug it in.
A machine as simple as that, can spark and ...welll.....the rest is history.
You would be amazed how many electrical appliances and even battery operated smoke detectors cause small sparks when starting up.
Gotta be way cool about that stuff.
OUTDOORS IS THE ONLY WAY TO GO :) :)
