a real sign of spring

OK, over the last few weeks I've seen geese flying, ducks paddling in the river, robins shivering a couple of weeks ago, flowers blooming, trees blossoming. but today I saw the really, real first sign of spring - kayaks on the river.  There were two of them, one bright yellow, one splattered in rainbow colors.  The people rowing them (or paddling - not sure which is the correct term), one in each boat seemed to be having a really good time, not working too hard, just gently moving along.  It was a beautiful sight. Now I'm thinking if I don't have the nerve to ride a bike any more maybe I could try kayaking. I've paddled canoes but never a kayak. Hummm...
