I've decided on August 5. Details will be TBD pending research, MnDOT's summer construction schedule, and any interest in non-road activities.
As I noted in my previous comment, the Twins have a home stand that weekend, against the Rangers. The Saturday game time is still TBD, but in the event that day doesn't work out, and for those who may come into town the day before, the Friday evening game is at 7:10 CDT.
As for what will be part of the meet, I'll leave that in part to interested attendees. I'll put a poll out later inquiring as to what folks may be interested in seeing or going to.
