Loon calls can be heard at Mercer's traditional event

MERCER - You will find some of the best calls of the wild at one Northwoods festival. The only difference is that the sounds come from humans. And you'll only find it at Loonfest.

The Mercer tradition is in its 34th year. About 250 craft booths cover the grounds.

There was a lot to see but most of the attention was on the sounds.
