Who Let the Frogs Out?

I'm not sure when Tom and I first noticed the frogs at night. I think it may have been a couple of weeks ago. Anyways they are LOUD! They croak all night long. The funny thing is that they will be croaking and all of a sudden they stop. *Silence* And then they start up again. And believe me that they are in sync. When I have trouble falling asleep I just lay there listening to them and I actually find it relaxing.
