Bring a bike lock.  We will actually go into the preserve for about 15 minutes to see the turtle exhibit and view some of the wildlife at the preserve.  The ride will include three miles on Dune Road, and a stop at the Beach Bakery.  I have two extra bike locks in my car.  Speed will average about 14mph, depending on wind, road conditions and rider ability.  Check the ride calendar day of ride for changes, which would be posted by 07:30am.
