On line pre-registration is projected to open early June 2013.
It is suggested that you arrive early on site to check in for pre-registrants and even earlier if you have not yet registered. There is a limited number of life jackets (which are required) on sale on site for $8. Inner-tubes are also available on site on a first come first serve basis. Registration is a measly $7. Also, there will be a limited number of Big Float t-shirts available.
