My wife & I play around with these from time to time. I've not seen this one but I'll check it out when I get home. We will be doing the Muddy Buddy (not an AR but still hsould be fun) at the end of this month, the Ocmulgee AR at the end of July, and the Bald Eagle Burnout mid Aug. We did a free race a couple weeks ago over on the Oconee that a local animal doc put on to introduce some friends to ARing. It was really well done. And free!! My wife and I did poorly - the first race of this year and we were too busy trying to go fast instead of thinking - but it was a good time.
