If you've ever noticed your kids' compassion when it comes to animals, this event is for you.
Celebrate the return of wildlife to the river by adopting a fish, naming it (Wanda, anyone?) and releasing it into the river. Fish wranglers will be there, just in case you can't keep your grip on the slippery fellas.
