Looking for spring

I keep looking for a definitive sign but everytime I think I see one it becomes covered with a blanket of snow.  Luckily my peach tree is not so easily intimidated by the weather.  Inside my seedlings can't be swayed either.  As I start to tenatively move some of my starts out under low tunnels of row cover and place selected seeds into the ground I can't help but wonder if winter will ever give it up around here.  I'm going to use floating row cover and walls of water to push my season a bit early.  I'm wondering what other extension techniques gardeners are using.
