Matt,
www.udpl.net has some basic info and a map to where we shoot. As well as a list of rules and such. All of our matches are at the FARM, and we shoot a 3 gun about once every 3 months.
If you have any questions PM me, and I'll see if I can't answer them. I'm the assistant match director for 3 gun so I figure I should theoretically maybe know something.
Seriously though, they are very fun matches. This next one is going to be 9 stages. Including an evil stage with a mover and a stage where you have to nail a steel target at 75 yards with your pistol.
Should be lots of good fun.
