The festival has grown in size over the last few years, I think this is the fourth one. The guy owns 400 acres or so and jams on the harmonica. My friend's wife sings in the Magic Mama Band listed on that link and they really got the crowd wound. One guy later on decided to walk around the grounds just wailing on his guitar.
Gonna take the kids next year, had to check it out first.
Later on, we invited some band members over and they played till about 4:30 in the morning at our campsite - hence the three hours sleep. You know, it was so nice to know there are people out there that just love music. It was nice to talk music with people, and it was really cool, the owner of this farm doesn't want any money, he rents spots to local vendors and such and then he pays the bands travel money from the money collected. That is rare.
