ICCM 2016 will take place in University Park, a city in the heart of central Pennsylvania. To travel to University Park / State College, it is easiest to fly into University Park Airport (SCE). The airport is served by American Airlines, Delta, United, and general aviation. It has direct flights to Washington (IAD), Chicago (ORD), Philadelphia (PHL), and Detroit (DTW).
Some travelers might find that flying into Pittsburgh and driving to ICCM (about 3 hours) and then on to Cognitive Science in Philadelphia, may serve them. Or, some folks may find flying into Harrisburg (MDT, about 1.6 hours away) significantly cheaper. However, using a rental car from the respective airport is advised. There is also bus service from NYC, Philly, and Pittsburgh: From Pittsburgh, for example, there are at least two Megabus services, leaving from downtown Pittsburgh. You are advised to check the schedule and arrange for transportation before committing to flights. Pittsburgh (airport) is 3hrs away by car, Harrisburg about 1 hr.
