I go to Pelican Point, I am getting toward intermediate level and glad to help if I can. I find many people are great and willing to help, but it feels rude to just ask strangers to answer questions even though they may love to help.
So I had a lesson from Nick at the Pelican Point Windsports setup there, he was very helpful; and the Beginner to Winner DVD is really good (though I am going NUTS listening to the intros from Lars!

).
If you can get a few improvers together, some mutual help is likely to to be very effective. I suggest a flyer posted at the 2 locations would get a group tegether in no time.
