You know it's spring when ...

... the cats come in with muddy paws. 

... the buds start swelling on the lilac bushes.

... there are spiders in the bathtub. *shudder*

... you start thinking about weekend road trips.

... it smells like mud outside.

... you put the snow shovels back in the shed.

... kids start playing in the park next door again. 

... it gets harder and harder to stay at the office on sunny afternoons.

... you wake up in the night to the sounds of rain and spring peepers.  Peeeeeeepers!
