I might be in the minority, but it would actually be cool to swim through the Paradise Pier lagoon as part of a triathlon. How many people can say: "I swam in the DCA lagoon!" ... legally, too.

At least I know one of my "million dreams" would come true at a Disney park if given that opportunity.
;)

Couldn't one assume the event organizers and Disney have already thought about health and safety concerns regarding the water and lagoon's bottom before approving event logistics?
