Thank you for visiting the 250 Miles Crossing Philadelphia web site. We noticed that you are using either a phone or a tablet or you might be visiting this page to get more info on internet speed limitations.
This project makes it possible to see and hear recorded tracks in Google Earth. You do need a pretty good internet connection for that and a browser plugin that is not available for phones and tablets.
So in case you still NEED to see something of this project RIGHT NOW, you can watch this video to get an idea!
There will be lots more, so make sure you visit this site again on a computer.
Hope to see you soon!
