Frogs Have Started "Croaking" in Michigan

This was the first entry in our looseleaf notebook journal that we kept last year.  Here is what we wrote:

Frogs Out!!!
Rain off & on all day.  It rained hard from 4:00pm to 6:00pm. We had a massive thunderstorm.  It was approximately 46 degrees Fahrenheit according to our La Crosse Technology monitor.  .  Channel5 News says that it was 36 degrees Fahrenheit in Saginaw, Michigan.

This is the first that we’ve heard the frogs croaking in the swamp in the backyard this season.  It is refreshing to hear them again after a long winter.
