Yes, Sunday is the 4th. I don't think Joleen and I have plans for that weekend yet (probably the only such weekend this year). The Isotopes as a class have elected to restrict their "Championship Series" racing to April-October on Kerr Lake. If any Isotopes sail at Jordan lake, or in March or November, they'd register as Open Class, not Isotope. This affects throwout and trophy-count calculations as well as scores. Other boats are, of course, welcome to enter the Open Class as well.
