Signs of spring

I noticed a new sign in the part a couple days ago.

Today was the second day the Busy Bee was open. They were doing a brisk business as people were enjoying the warm day we had today. No jackets were needed.

I heard the aircraft with the glider wing (what is the proper name for this aircraft?) today. It is not a vehicle that would be much fun in the winter.

Is it too early to start planting things in the garden?
