If you have the time and are up for an adventure, tell your GPS that you want to "avoid toll roads". If you're feeling really adventurous, you'll do this while heading through West Virginia. I have no idea where we were, but eventually we ended up on Interstate 70 and were able to make up for lost time.
Our first day's stop was in Carmel, Indiana (right outside of Indianapolis). The town there has an outdoor waterpark with a brand-spanking new flowrider. It was a double, but sadly enough, they used the barrier. However, the ride was so nice and smooth, it was totally worth the smaller space. The staff was great, and we're hoping to hit it on the way back east.
Tomorrow, off to Minneapolis. Not riding, just a good place to stop for the night.
