I found it!

I found the elusive entrance to the Brooklyn Bridge on the Brooklyn side! Turns out I rode right past it last time when I got "lost" and found myself on the Manhattan Bridge. While the Brooklyn has WAY more people on it, it's a much easier ride. Somehow, it's not just straight up and then straight down like its sister bridge, which you can see upstream. There are hills on this bridge. But that's nice because you don't feel like you're going to die at the midpoint. And it's shorter. Much shorter. It must be shorter.

I think I was in no fewer than 10 tourist photos today.
