Are you going to the NSTA STEM conference? I am envious! I am only 2 1/2 hours away and due to school budget I probably will not get to go. Doesn't help that our last day of school is that Friday with semester exams that week.
A few yrs ago I went to the national NSTA in St Louis. I walked every day to the convention center from the Drury Inn which is by the baseball stadium and the Arch. It was an easy walk.
