GoddessPlace, like many other themed forums, has had a fair share of coast-oriented event discussion. As a corn-fed Hoosier boy, that sucks. I was always hungry for Midwest events. Well, here are some:
Pagan Spirit Gathering
-- An, apparently, huge event in Northern Illinois.
Lothlorien Nature Sanctuary
-- Southern Indiana, and they have a bunch of events throughout the year.
Earth Traditions "Oasis"
--- Also in Northern Illinois, I believe.
If you have any other major events to add, GoddessPlace has a great forum to share.
