It's always a good idea if you can pm at least one person to arrange a meeting point or perhaps state what you're wearing or riding and what to look out for.
Some of use have BM hoodies and tshirts with our names on, which we would wear to meets, although I know this isn't always practical, but if a group knows roughly where they will be meeting ( thinking of the Big Ice Cream cones at Matlock Bath) then anyone looking like they might be part of BM can hopefully be found

It's a shame when people turn up for a day out and find out they were so close, yet so far to meeting new friends!
