Hi everyone! We're in Columbus right now and having a great time. Thanks for all of the advice so far. We've enjoyed everything suggested.
My boys (5 and 7) had asked if there was a stream they could play in? This is something we often do at home- looking under rocks, scooping with a net while wading in, etc. Is there any place like that around? A state park maybe? Extra points if it's on the east side of the city back towards Pittsburgh.
