Have barn, will party.
My brother and sister-in-law hosted the first annual "Barn Bash" at their place in Wolverine this year. The mandatory costume requirement was taken seriously - especially by Brian, who grew a goatee, then trimmed it to a mustache in order to become "Magnum PI". I was a witch, although I never got around to making myself look very witchy!
They had all the makings for a great fall party...bobbing for apples, kegs o' beer, spooky decorations and of course, little goblins (kids) dancing to bluegrass music! After the kids were settled into the house (or camper, in Isaac's case) - the band Rootstand took over the stage. They were great and it was awesome to have a band just for family and friends!
