My husband had a layover in Casey for a night and walked to all the big things sending me so many pictures it got old fast for both of us. He gets to fly to some awesome places as a corporate pilot, other times he goes to Casey.Our family went camping at a Koa camp spot in Casey IL. It's 3 hours south of us in the middle of nowhere. Absolutely nothing to do except look at all the "big" things in the small town. Like the largest mailbox, largest birdcage, largest pitchfork, yardstick, windchill, knitting needles.....it was a long boring, miserable weekend.
My oldest really wanted to go to garden of the gods. It was another 2 and1/2 hours from Casey. So about 5 hours south from here. You would probably need a couple of days to visit and see most everything.
