There aren't many activities these days that are FREE.
If you can stand a bit more sun, I would like to invite you to attend Warbirds Over Iowa, the Cedar Rapids Skyhawks radio controlled military aircraft fly-in.
The event is free to spectators, and is also a charity fund raiser for Eastern Iowa Honor Flight for those that wish to contribute.
The event will last most of the day this Saturday, July 23rd (bad weather will move the event to the 24th).
Here is the flier that shows how to get to the Skyhawks field north of town.[Download not found]
