[TheForge] Yellin work in Philadelphia?

[Marc Godbout]

We're visiting our son in PA next month and spending the day in
Philadelphia. I'm the only real metalhead in the family, so we can't
spend the day looking at the great ironwork there. But are there some
good examples of Yellin's work I could probably steer towards? Or
really any great work or works that might get more than an "Oh that's
nice" out of the family?

Thanks.
