Hi All - I'm thinking of a short road trip (800 miles) because I can't imagine my crazy 2 yr old on a plane just yet. Want to take the little one and my 7 year old to Memphis but figure we'll need to stop somewhere about halfway. What's a reasonably interesting place to stop for a day with two kids before gearing back up for Memphis? We won't be doing this until April of 2008. Thanks for any and all help - this is my first foray into non-flight travel!
