I've just signed up for this year's DGR. Not the A10 through Edinburgh this time but the 1913 Douglas on a solo ride. Bet it rains!
I've communicated with them almost every year to get the forum team listed as "Worldwide Ride" and have a friendly relationship. I've also shared some of our members' frustrations, but not sure if that changed anything. Just try emailing them. They will likely respond to a civil exchange.Richard L.
