Sign of Spring?

I'm back home in Fort Worth. There's not really much sign of spring except that one of the nearly 100 American Goldfinches at the feeders today was bright, bright yellow. I think he's a bit too early, especially since the ground hog saw his shadow today (or at least one of them did). Although it never got much above 50 degrees today, it was a lot warmer than North Carolina's freezing, icy weather.
