Next Summer my daughter and I will be driving from Vegas to Pittsburgh on a 3 week vacation. We love roller coasters and Theme parks. I'm trying to plan a few must see stops on our drive and I'm curious what are the must see coasters that we should stop at along the way.... I have yet to even plan a route or other sights, but when me and my stepdad did this trip in '98 we took a northern route to, and a southern route back. I would really like to hit a few parks like every other day depending on locations. So, if anyone has some suggestions I would appreciate it... Thanks!!
