The architecture of Central Park

When I was in NYC on business, I ended up with some free time at the end of the day and decided to meander towards Central Park.  I had been in New York City before, but had never been to Central Park.  I had a very basic map in hand of the city, which gave little detail on the Park itself, so I was rather happy and surprised when I stumbled across the area around the Bethesda Fountain.  It is a beautiful fountain and I was very intrigued when I found this little area under a bridge.  It has all these nice arches and the ceiling was alive with all these beautiful orange lights - it just screamed HDR to me.  While I was setting up, there was this young guy standing around with his guitar, playing some Beatles songs and chatting with me.  He was pretty good, and the acoustics here were excellent.
