Behind the visitor center they had an outdoor bowling lane made from the granite. It was a prototype that never really took off. The bowling balls were a light foam- that would be why my little man could pick one up.
We met up with a friend whom we don't see too often and had a really nice day, besides the cold temps.
We took the long way home and traveled through the mountains and stopped at Ben and Jerry's for a sweet treat. A great way to end the day.
