Yea, what everybody else said.
Or try this, set up the camera on a tripod, set up your gear (or not...I'll explain in a moment), set the timer, and "play DJ". Do this a few times, the candid shot comes from you not knowing when the timer is going off, but you still will need a few shots to find a good one. It's a cheapy way to eventually maybe find a good action shot.
(Here's where I ruin the Facebook experience for all my friends)
This shot (my FB profile pic), that I then played with in Photoshop, is a posed shot using the method I explained above. Not only is it posed, but there is no gear in front of me...and not only is there no gear in front of me,
but I'm not wearing pants either...seriously.

BTW...the picture I use here as my avatar is a real picture from an event and I am wearing pants...I can prove it.
