I'm right around the corner from you in Fraser (Masonic and Kelly.) There's a couple of HBT'ers in Roseville, most notably MustangJ who heads up our bulk grain buy. We get together and brew at his place on occassion, or just hang out at Dragonmead.
The East Siders tend to communicate between each other, planning brews and gatherings on the Michigan Masher's Subforum here. Or we have a facebook group.
