I joined a local club that is welcoming more spey/fly guys, so...
We'll probably do a spring 2013 in the same general area...but...... have it greatly expanded.
We had an informal thing this past spring near milwaukee for the first time. It was awesome that Woodlander, HERON, and Riveraddict contributed. Wow.
You could probably tie your journey in with some fishing on 3 different rivers; by mid-march theres fish in each of em.
Heres a few pics:

Of the many places a gathering like this will be promoted, you can be assured you will read about it here first.
Oh yeah....if you fish the brule the week before it closes I'll up there and would be happy to meet ya.
