A great way to spend an afternoon with the kids is to feed the ducks and geese!
Safe things to feed ducks is:
Corn (Fresh, frozen or canned)
Duck pellets (sold online or at pet stores)
Lettuce (or other greens torn into tiny pieces)
Frozen peas (defrosted)
Bread can have a bad reaction to a birds digestive system and can mold the water.
Here's a list of places to feed Ducks and Geese in and around Louisville, Kentucky:
McNeely Lake Park
Long Run Park
Cave Hill Cemetary in the Highlands. Most people would be opposed to taking their kids to a cemetary, but Cave Hill Cemetary has a very deep rich history and even does tours.

There is a large pond off of Lynn Station Road with a small bridge for feeding ducks and geese.
