Activity in the Bay!

Today I am stuck indoors learning photoshop, so haven't moved since early this morning (and it looks cold and windy outside, our cold being about 18 deg, lol). So luckily I happen to here a commotion on my front lawn, which is the bay, and I noticed some boating activity. Don't know exactly what they were doing...is that a dredger?? Oh well, watched them going round in a circle and then they left, so that's my blip for the day.....now back to learning photoshop!
