4.5 votes for Mt Graylock, for the win. That's the location.
I counted Formula413 as a half vote for Graylock, based on his notes in post #20.
I voted for Worcester, Springfield and Mt Graylock, but didn't mention it here till this post now.
Sat vs Sun: 1 vote for Sat, 2 for Sun, so it looks like it will be on Sunday.
Changzuki, you certainly earned my respect with your excellent showing at this year's GGP. I'll be more than glad to see you at the Mt Graylock event if you are able to make it.
Sheepdog44 provided me with a link to the route:
Mount Geylock MPG rally course - Pittsfield, MA
I needed some time playing with the map to get the hang of it. Magnified enough, you can see each mile marker on the route, and use that with the "Cue Sheet" which shows the turns. The elevation map at the bottom of the screen shows the summit at the 30.4 mile mark.
Our event is shaping up!
