Nothing to be concerned about. If it bothers you brush the rust off with a wire brush and squirt it with some Rustoleum. Just be sure to pick a pretty color!
The picture in my avatar is of the Houston Ship Channel and was taken from my backyard. I like to sit outside and slap mosquitos while watching countless supertankers, barges and cargo ships of every shape and size carry all sorts of deadly toxins to and fro. It's really beautiful at times.....just don't eat the three eyed fish....
