You guys are scaring me!
I've got approx. 20 boxes (23" - 15") and those I use all the time for work.
I suppose I better include and oxy/acetalene torches and related gear, too!
Then I have a few boxes for around the home for the wife to use when I'm on the road and not about for her amusement...
I better sit down during the coming few weeks and start (And finish!) an inventory (Thanks kmaysob!).
