Points of Interest Map or App?

So I'm flying the family from Wichita, KS to several locations in Florida including Tampa (first), Orlando, and Key West. Wondering if there is an iPad app or map which will show points of interest along the way. We'll be flying over some pretty historic land in the American South and it would be nice to know what we're flying over. Any ideas?

Google maps? Google Earth?
You can highlight points of interest in your preferences by selecting Wikipedia. Just need to have a connection to the internet via 3G.

You'll most likely be flying almost right over X35 just before Tampa. Cheap fuel and people who always like to look at RV's. Call me if you need anything at 352-427-0285.
