Sling at me... please.

During my last few days of slinging in Kentucky I was interested in getting a shot from the target's perspective. Curiously, I couldn't find anybody willing to hold the camera. Weird. But there were plenty of people willing to sling at me I noticed. We'd open each session with "I want you to aim for my head (only tennis balls here). It's amazing how sharply everybody's target percentages jumped when they felt the motivation to actual hit the target... here being... me.
