Well actually non-local folks are also invited, but I (mostly) don't expect them to attend.
Here are the (admittedly vague) details I have:
July 3 - dusk - Royal Oak - near Red Run Park - S. of 13 Mile, W. of Campbell
Encouraged are the bringing of chairs/blankets and possibly even beverages
Let me know if you want to coordinate a meeting-up of some sort.
