My 3,000th photo on Flickr: Watching the sunset, Battery Park, originally uploaded by Dan Nguyen @ New York City.
I started using Flickr back in 2008 but joined the Pro version (which allows you to upload unlimited photos) late in 2009.
This photo, 5 minutes from my workplace, is number 3,000. I’ve seen the sunset dozens of times here but it never gets old.
