I'll never knock Philly for being grubby ever again. Can you believe these photos were taken inside the city limits? This is Wissahickon Valley Park, the north-west portion of Fairmount Park. If you can ignore the distant hum of air and road traffic and focus instead on the birdsong and wind in the trees, it really does feel like you're out in the middle of nowhere.
One of the trails takes you under the Walnut Lane Bridge, which is pretty awe-inspiring from this vantage.
After leaving the park one day, I walked halfway across it before I realized where I was. This bridge is only a hundred years old, of course, but there's something so majestic about it, like a Roman aqueduct. You're so far below the traffic that it's easy to pretend it hasn't been used in centuries.
Following the trail, there's a wooded ridge on one side and, on the other, Wissahickon Creek far below you. At the top of one of those ridges (Mom Rinker's Rock, according to Wikipedia) there's a statue of a man I took to be William Penn, with the word TOLERATION inscribed at the base (also according to Wikipedia: the statue isn't meant to be any Quaker in particular).
You know what this means? Seven years of good luck.
