Despite being very close to Rivvy barn I don't go that often to the big meet on Sundays, I tend to go during the week when I have days off.
Knott End on Wednesdays is usually very good with plenty of bikes, and quite a few of the Pennine Massive seem to go frequently so I sometimes bump into a friendly face or two, but generally I just go & end up having a brew & a chat with anyone who'll put up with me for a while!
