Ed, I was just wondering why the dolphins are coming up the rivers this time of year. Could it have anything to do with the runoff of all the salt and brine on our roads used to melt snow that gets washed back into the streams and rivers making the water more salty and suitable for ocean creatures to survive in? What’s that salty runoff doing to our environment in general?

You’re right that the runoff is none too good for nature. But dolphins, being natural and all, probably aren’t that attracted to it either, even though it’s salty. I’m pretty sure they like clean salt. —Ed. Note
