MELTING......Melting......melting

This stream is a few blocks from my house and is running pretty well as it is fed with melting snow. When I was a kid these waters were so polluted and foul that I wouldn't have dared to touch them. In the last 40 years it's been cleaned up a lot and what used to be a low rent area of town is now a spot where people have a "water feature" on their property and can therefore charge more.
