My wife and I will be renting a car and driving to South Dakota in june when school gets out for summer. We will be taking our daughters, ages 6 and 3. Does anyone have an "in" with a rental company that would be willing to help us out? rebates? What rental company would you choose? Just like alot of people, finances are tight for us. Also, are there any "must see" places on the way? I've never made this drive before, and would appreciate any info/advice the NWFA braintrust can offer.
