Very touching article. I just read the FR first thread on 9/11 as it happened. It still brings on goosebumps and that feeling of total horror.
When I suggested it to them during our last visit to what is now a full blown National Park with a visitor's center, I got the excuse that the unmarked road nearest the park to Shanksville would remain unmarked because the locals didn't want the traffic disturbing their little community.
What a crock, I thought. Build a toll road out of the south end of the park to connect to the road to the memorial chapel and Shanksville. Share the proceeds with the town and they would be happy to have the extra revenue. But I think like an economist and not a government bureaucrat.
