It is the Annual 'Take to the Lake' paddle on Shaker Lakes - the lower lake by South Park & Coventry.
You can bring your own kayak or rent theirs for $5.00.
The over all event runs from 12:00-5:00pm
I will be there from 12:30 through 3pm and maybe later.
I'll be bringing 2 extra kayak for anyone who wants to try them out.
Presume you'll get a bit wet from paddle splash, so bring a change of dry clothes. The person who doesn't plan on it is the person who falls in the water. :)

At the time I posted this, the 'More info here...' link was broken. You now know what I know.
I've been told walk-ups are allowed.
Hope to see you there.
