I carry my own arrow (I know, I'm a geek). Most NYC schools don't have an AP arrow at the table. They all tell me it's for financial reasons. When i tell them how I made mine that blows the money thing out of the water.

It's one of the blocks my kids used to play with when they were little. I printed "POSS -->" on a sheet of paper and "<---POSS" on another, attached them to the block with clear tape and there you have it. The "POSS--->" and "<---POSS" mirror each other so the table crew sees the same direction we see on the court.

And I'll say it again: I know, I'm a geek. But it works.
