In about a month (May 17), 2 of my high school buddies and I are going to fly out to Vegas to meet up a friend who goes to school out there and drive his car back home to the DC area. We don't have a whole lot of restrictions-gas money is being covered by the guy with the car's parents, so we just have to pay for food/hotels/souvenirs. None of us have jobs set up until the beginning of June, so time is not a huge issue. We're comfortable driving a lot in the car (it's an '07) and all 4 of us have driven at least 8 hours non stop before.
Right now, we're thinking:
-1 night in Vegas (we've all been there before and none of us are 21 yet, so there's not a whole lot we can do that we haven't already done).
From there, we're trying to decide between going up through Yellowstone, then to Mount Rushmore and then Minneapolis/Milwaukee/Chicago or to go down through Arizona/New Mexico/Texas/Oklahoma and going through places like Memphis and Nashville.
We'd like to end up going to Cedar Point in Ohio and at least 1 White Castle along the way. Any ideas?
