Spring is in the air...

Got to dash, but... although the pic is poorly cropped, I took this today of a Daffodil and liked how you could see inside the flower... Spring is almost here, I'd say it was here in some parts of the country... but what defines Spring?... Temp., Flowers, insects, Frogspawn??

I think Spring starts at different times for everyone.. I think of lighter nights, lighter mornings. Insects, bird song, frog spawn and of course Daffodils! :D
