Changing Skyline: Architects convention won't find much architecture in Philly boom

There's a big national convention coming to town that will give Philadelphia a chance to show off what a spiffy, exciting place it has become.

Some 19,000 of those exacting design minds will be prowling our streets next week, taking measure of our stone citadels, peering at our construction sites, and generally giving us a professional once-over.
