Walking from the hotel to the ISTE conference (with a few detours), I passed some beautiful murals. Philadelphia is full of murals and other art work. I am always impressed by cities that value art. Public art is accessible to all. It speaks to the emotions and elicits laughter, a smile and even tears.
As Philadelphia is a very flat city, walking is easy, but benches are available for those who need a rest or just want to stop to admire the architecture.
William Penn stands atop Philadelphia's City Hall overlooking the city. He must once have been able to see far and wide. Now modern buildings tower over the city obstruction his view in some directions.
