What do you mean there are only 4 more weeks of school? I'm a little shocked about that one, I don't know about y'all.
In the never ending quest to keep children occupied and not fighting over the summer, I give to you a few ideas you might persue around our little corner of green country. What's better- you can do them all on just a little of the green stuff.
Tunnels & Skyscrapers: Did you know there are underground tunnels that connect the buildings in downtown Tulsa? (They also have them in Bartlesville!) My kids and I just learned about the Tulsa ones at the end of last summer, and didn't get a chance to explore that yet. But it's on the list this summer!
