I have to say it, for all of the idiots, a***oles, and broken glass, Philly has got some great things going for it for bikes:
Ben Franklin Parkway, Chinatown, Independence Mall - my fav way across town, a nice view of the city coming from the Art Museum down the Parkway, wrap around Ind. Mall to head down to South Philly and my Phil-billy neighbors
East/West River Drive - gets a little smoggy in windless rush hours, but is a great way out of Center City in general, truly beautiful... nice people, nice jogger ogling
Forbidden Drive - a little slice of heaven within city limits, great for hybrids and trails for MTB'ers along the way, no cars, really nice people (!)
East Falls, Manyunk, West G-Town, West Mt. Airy, Chesnut Hill - great hilly residential sections for biking
relatively decent drivers - Philadelphians are cocky a***oles, but that's what keeps everyone from yelling and throwing things out of cars - I can't believe some of the stories I hear on these forums, you'd never get by in Philly throwing Coke bottles at people... watch out for NJ drivers though, they suck!
cops - that don't bust your balls for sign/light offences... the bike cops run lights themselves! I wouldn't talk smart to them, though...
weather - that is all over the place, but doesn't stay in extremes for but a short while
me - the coolest cyclist in the US...and some say... the WORLD!
I left out the Valley Forge ride, as I've never done it.
C'mon Philly people, post your rides and high fives!!!!!!!!!
