I can probably make either weekend as of right now. In fact, I may be in the area a few miles south of East Jordan about that time. My preference would be whichever weekend falls closest to an outing the Midwest Large Format Asylum may be doing in the UP around that time. I've posted a request in their forum for more information and will let you know as soon as possible. June is a marvelous time to be in that area.
Sounds like a good time. I'd love to see a platinum demo and I could probably bring along chemistry for cyanotypes and Van Dyke brownprinting in addition to the wetplate stuff. Wilderness State Park was on my list of places to visit this year so this is all working out nicely for me. I also have an old friend who lives in Cross Village and it will be great to see him again while I'm in the area.
