Air arc in utah??

[UNSTUCK]

Boo! Black boogers are the best part of my shower each day (well except for the ones that I don't see land, and end up finding them later on smeared into my towel, but I digress).

When i grind that much i'll set up a fan out side or stand right in front of the AC and grinded away from it. No more black boogers yay!!

black boogers are a bad bad sign... aluminum oxide grinding dust is seriously bad stuff to get in your lungs. If you've ever done any grinding areas with direct sunlight and hard shadows you'll have noticed how the air is just churning with all sorts of dust. Pretty crazy, always use a mask.
