Doug, 
absolutely one of the most fun things to do both from a participation standpoint and from a photography standpoint.  For a bunch of the shots, the layout allowed me to lay on my belly to catch them coming at me 3/4.  I love that perspective.  Of course, as I was laying there, Moxie was licking my ears so I did have a bit of distraction  

.  Here's an example of how a Rottie does it.  Not nearly as elegant but plenty of attitude

 If you get a chance to watch/shoot a coursing event, I highly recommend it.
