Thanks for updating the link. I should point out that there are serious errors on that section of the city as well. For instance, it's got "Drexel University" where Penn's Law School is. I checked my neighborhood and it's just as bad. It's got the Bryn Mawr R5 train station tagged as "Rosemont Station". There's a second "Rosemont Station" tagged about where the Stadium station on the Rt. 100 is. The actual Rosemont Station R5 station, roughly midway between these two points, isn't tagged at all. Nor is the Rosemont stop on the Rt. 100 line. It's great that you've got hundreds of thousands of people working on this project, but is anyone actually checking that the data they're entering is accurate? Perhaps more seriously, the map indicates that County Line Rd. joins E. County Line Rd. in Rosemont by forming the border of Austin Park. That's completely inaccurate. The park extends all the way to Lancaster Ave., and the line which appears to be a continuation of the road is in fact just a sidewalk through the park. Walt Attachment:
