The Second Amendment does not guarantee that all people can carry any gun anywhere they want. Past Supreme Court decisions have put limits on that right. For example, in the Heller case of 2008, Justice Scalia wrote "Like most rights, the Second Amendment right is not unlimited. It is not a right to keep and carry any weapon whatsoever in any manner whatsoever and for whatever purpose."
I'm glad that Giant Eagle is asking people who carry guns to stay away. They should go further and ban guns from their stores. They're a private company. They have that right.
Guns make us less safe, so the fewer non-professionals there are toting guns in public, the safer we all are.
Schenley Drive in front of Phipps also has a parking-protected bike lane. But it's short. More of our bike lanes need to be either parking-protected, bollard-protected (like Penn Ave downtown), or planter-protected (as in Akron, Ohio).
If a shuttle like this is not built, the car traffic on Irvine St and the congestion at the intersection of Second & Greenfield and at Second & Bates will get even worse than it currently is. Public transit such as this proposed shuttle helps reduce the use of single-occupancy cars and the noise and air pollution that goes with it. Think of the shuttle as a congestion-reducer. Bike trails and bike lanes help get people out of cars, also. The shuttle needs a stop at Panther Hollow Lake!
A note about names: Junction Hollow runs north-south. Panther Hollow runs east-west.
Charles Black's comments are unreasonably harsh. The CMU campus has a few eyesores (Warner Hall, Wean Hall, and Hunt Library) but most of the rest have a consistent and pleasant Hornbostel architectural style.
Compare to Pitt, which has a higher percentage of ugly buildings, and a much less coherent campus.
