Interest in navigation clinic?

For those that may be new to the sport of adventure racing, I am considering having an "Adventure Racing 101/navigation" clinic sometime prior to the race.  It would most likely be on a Saturday morning.  We will discuss what adventure racing is, basic navigation using topographical maps (like the ones you will use for the race) and plotting UTM coordinates.  After the "classroom" instruction, we would go out and do some navigation field practice.  If you are interested in attending, please drop me an e-mail ASAP so I can get something scheduled.  There would be a nominal fee ($5) to cover the costs of maps and supplies.
