Our goals were:
1.) Go to places we hadn't been to before. (we live in Boston and we've already been everywhere in the northeast, so excluded the entire northeast.)
2.) Go to places we wouldn't otherwise visit. (for example, I would never buy a plane ticket and make a special trip to Mount Rushmore, but if I'm driving through the area I'll definitely stop. If it weren't for this trip I'd probably never go to places like South Dakota, Iowa, and Montana.)
3.) Go to games at as many baseball stadiums as possible. (we saw 10)
