Dimitri and Willy...
Well, I gotta tell ya, when the water goes down a little bit, you know as well as I do, I'm sure, that Yuba is the perfect place for that!
Warm, grab bag of wind, etc...
But I also, have to say, please come to the beginner day with them, nobody has to stay a part of the so called "Itinerary"... The cool thing about the 16th and 17th of june, is(could be) that there is a purposeful learning atmosphere... It's always easier when you see others struggling the same as you... Have your kids bring their friends...  Dimitri, I know efforts like this one are old hat for you, been there, done that, right... Well, let's do it again! 
Take care... 
PS Dimitri... I am blown away by what Radius has become... I salute you with 1000 armies! Amazing!
