New York's Forgotton 'High Line'

"When freelance writer Joshua David and painter Robert Hammond first followed their curiosity over a barbed-wire fence onto the High Line five years ago, they found themselves on an elevated avenue of greenery that overlooked the art galleries of Chelsea and the designer boutiques of the Meatpacking District — two of the city's newly fashionable neighborhoods... The abandoned railway, the pair realized, could become a place where pedestrians could stroll unimpeded for 22 blocks, suspended nearly 30 feet in places above the hustle of the streets."
