The deep slush/ice layers in my driveway are melting off in the last 24 hours of warming temps. It actually got up to about 50 f. yesterday. The snow bank by the sidewalk is only about two feet deep now.

One concern I have for coming spring is that West Nile virus has reached Montana. I have a small pond by the deck that the dog likes to drink from. In the past I've put in small goldfish to eat mosquito larvae, but I'm wondering if I should add something else to the water to more effectively kill the mosquitos... but don't want to poison the dog. Anyone have a solution?
