It's not too bad. If you're coming from I-76, you're getting off on the stop before the south street exit, right (I don't remember the exit number) ? It's a short drive to make your way westward up Walnut Street. The parking area is about a block away from the school itself. The only thing that bothered me when I first drove around the city, was watching out for wayward bike riders. There are a fair number of them in the morning, so watch your right mirror and turns.
