So far it's a tie for "most handtrucks used" at a staggering "one." I know you guys can do better than that - heck, I managed three in my One-Ringer hanger bay set.
On the "Most Creative" and "Most Nifty" fronts there's a bit more of a challenge brewing...for example, check out this great Deckchair by David Pickett!
So what are you waiting for? Time to put your handtrucks to good use! Go build something!
