Exciting news here, mark your calendar for May 19/21, 2006! We have much to do and plan to get started with a work weekend coming up this Sept. 17/18 to do some clearing for sections in the creekbed while it is dry and maybe we can pile the brush in the creekbed and burn it. We need to clear out lots of small trees so that spectators will have a good view of the action. Bring a chainsaw if you have one. Cabins are available for use if you can stay over.
