Well, the Hudson River near NYC is now open for swimming above the GW bridge! We noticed a BIG improvement in just ten years.
Baltimore Harbor is full of crabs, and when water clears up between rainstorms, we have seen big fish swimming around, likely carp. Plus, there are MASSIVE feeding frenzies of fish on bait pods at certain times of the year. Very nice to see, so Baltimore Harbor is obviously improving. WTG!
