Monday Blues

Yesterday was a wet and rainy day here in New York City.  I wish I had captured a picture of the rainfall last night - between the thunder, lightning and winds it was pretty incredible.  Luckily when I left for work at  7:00 AM the rain had calmed to a lovely drizzle.
Here are some pictures I captured while walking through Central Park.

On a normal weather day you can see the skyline of Manhattan at the south end of the park.  Today you can barely make out the tops of some of the buildings.

Question for you out there - does anyone know how to make a decent watermark?
