Let's have a look at some of the sights in and around my neighborhood. (Click the thumbnails to see the full-size images.)
The flowering cherry trees are, uh... flowering. These are different from the famous Washington cherry blossom trees. Those trees are Japanese cherries. They are very pale pink, almost white; these are a true pink.
These gorgeous trees are dressed in the best Easter white.
Red buds doing nature's bidding, um... budding. At any rate, they're really purply-pink, not red.
And the dogwoods are blooming! They come in pink, too -- shades ranging from pale to fuschia.
So yeah, I think it's spring!
