Dan M (not on forums) acquired a second segment in/around the Twin Cities (near Maple Plain) lastyear. It's between mile marker's 147 and 148 of Highway 12 just east of Maple Plain.

Google map here.
He's running a clean up this coming Saturday, 4/28/2012, at 8:30am. Some will be meeting early for breakfast (not free) at Monie's at the western end of the segment starting at 7:30am (NW corner of US12 and Baker Park Road, near mile post 147).
All are invited and welcome.
Parking for the pickup is Monie's lot, toward the highway, away from the building so as not to interfere with other restaurant customers, there is plenty of room.
Feel free to RSVP on this thread. If you can, also drop Dan an email using this form as he's not a forum dweller.
