Bring your own lunch/snacks/pack-rafts/pfd's and paddles. If you want to dig up a five gallon bucket and bring some elastic/rope/webbing/surgical tubing we can do a little demonstration on making hand-paddles as well. And I'll bring my alpacka boats so you can check these out and see what you might want to save your pennies for.
Also, i'm hoping to post a sample map of the turtle river area in the next few weeks with 4 or 5 checkpoints labelled on it, and then go hang these checkpoints. this will let folks get out there and practice navigation on their own. The checkpoints of course will not be the ones used for the actual race.
Both the navigation clinic and the group pack-raft are free once you get into the park, although now that we're a non-profit and have lots of other (less revenue generating projects) afoot, we'll certainly be accepting donations if you feel the workshops were of good value and are so inclined. Please RSVP at firstname.lastname@example.org so we can have an idea of how many to expect.
