If we're talking 'side-patch clubs'......me for one !! :-0)
Mind you.....can't see us having many 'back-patches' amongst the ranks !! :-0)
Poor old Al's a full colour member of Ogri MCC. L'il ole me is only an associate. Don't know about other backpatch clubs, but Ogri is like an extended family and there aren't lots of rules either. Several Bird members (and my 75 year-old mother) have been to the clubhouse for various parties and rallies and all seem to have had a good time.
I gather the MCs are the ones with lots of rules, and you can't wear your colours into their territory without asking permission. I do know that Ogri had to ask permission from 'the big boys' to sport a backpatch in the first place 30 odd years ago.
I have to admit, the rallies we've done have all been at clubs that Ogri have close ties to, so I've never found any of them unfriendly. We did do one rally at an unknown club, Future MCC's Clay Pigeon Rally, with others from this forum as it was also our EOSB. Great time had by all, and no-one was unfriendly there either.
