In general, I think the National Park Service has done a good job in honoring the heros while respecting the privacy of the locals not to have all the traffic going through. It is a delicate and respectful balance. The local roads simply could not handle the traffic which comes to visit the site now.
Okay,I know what you are talking about. We would come in after going east bound through Somerset off (I think) St. Rd. 711. Rt. 30 makes more sense.
