MKL early entry deadline was yesterday. I just sent mine in, hopefully they will still accept it as early.

The race will not be part of the Endurance Sail Series this year. The 2009 schedule will be posted today or tonight. The first endurance race will be the Keys-100 on April 25-26 and the 2008 awards will be held during the event.

I drove down to Miami Saturday to beat the deadline. They still except entries as late as April 16th
