Hey there is a Michigan BattleTech Facebook group, which covers Grand Rapids, Kalamazoo, Lansing and Detroit mainly but there are I think like 300+ people on that.
That will help to track some people down, as you can at least post events, and those relatively near may travel.
I am in Grand Rapids, so your really only 1.5 hours away from us, so depending on timing and ( Michigan Weather LOL ) myself and our group could travel.
