Just found that I've by chance stumbled across the facebook group of the riders who meet at the petrol station on the MRR route lol - the Box Hill Salvos! A facebook group that I came across by chance a couple of days ago and joined online just because it was local, not having any idea where they rode or what pace (and the name somehow didn't make me think that it could be a workplace group or anything)... then just 30 mins ago I saw in my notifications that they were posting about the MRR!
In fact, I think it was only today (or perhaps last week) that someone on the MRR course told me that the people who meet at the servo are *not* MRRers - I'd been assuming, with all the spread-out cheese people there have been over the past year or more, that they were just a big cheese group meeting there as an alternative to Kaz's corner lol! So... they are not MRRers, nor are they likely very cheese pace
(I had noticed in the past that there was at least one group around that did part of the MRR route, so perhaps it was always that same group!)
