I would like to formally invite boats to my club's local Regatta- the Howard Prairie Regatta.  Typical Regatta weather is beautiful with highs in the low 90's and water temps in the low 70's all with consistent 8kt-14kt winds.  We typically get in five races and several of them are reasonably long. (I believe Tom Burden has sailed our Regatta and can vouch for the conditions - Tom?)
Here is a link to our club's website and the Regatta information will be posted soon:
http://www.rogueyachtclub.org/index.php?option=com_frontpage&Itemid=1Bob Aman (Rogue #71) and Jake Cartwright (UFO #27) have expressed interest in racing our regatta.  If a few of the NorCal boats would commit I think we would have some good one-design.  We are just six hours from SF Bay.
Camping is gorgeous right on the lake and is only $18-29.  There are other good accommodation options as well.  The Regatta Dinner is cheap ($10 each).  We do a complementary 8 gal micro-brew keg on Saturday Night.  The entry fee is cheap (I think $45 bucks last year).  Wet moorage around the regatta can usually be arranged without much hassle.
I have a couple people in our club that are thinking about switching boats and I am always selling the U20.  If we had some OD at our regatta, then I think I could get a couple converts over next winter to get a couple of those used boats off the market.
