You could jump on up to Kansas in April. They are holding their first of the annual Wave regattas there and really working hard at getting it off the ground.
Unfortunately, I cannot make that one as I will be teaching a seminar at the time.
Think about Put-in-Bay, and the rest.
You have been in some hot classes, so I know you will enjoy the simplicity of sailing the Wave so that you can concentrate on starts, tactics, mark roundings and windshifts.
