On the eve of the festival there's a jam session on Main Street in downtown Etna. Everybody is welomed and people bring their instruments, kids, dogs and camera and they all have a great time playing, singing or just watching. Sometimes some of the pros join in the festivities.

Some images from Jamin' On Main are featured in a short Squidoo article: http://www.squidoo.com/have-you-tried-bluegrass-jam
