A lot of the clubs down my way have limited number events (SE centre) 40-50 riders seems the norm and this in a lot of cases is due to restricted parking at venues because of the extra space that has to be left between vehicles. I am a member of 3 clubs, one in each of my bordering areas (SE, Southern and So Midland) and only one of the 3 have run any events as yet. Please bear in mind that a vast number of the organisers are older members (70+) and may not feel comfortable exposing themselves to a large number of people outside of their "bubble". It strikes me as being an ideal situation to get a few of the younger members to step up and run events until things settle down, maybe they will have a little more respect for the current organisers and appreciate the effort involved! I could probably join 1 or 2 more local clubs just to ride but I feel that is a bit silly in the long run.
Faussy, have you tried calling the club secretary of you old club and talking to them? After all you are renewing and not a new member per se. I think the no new member thing is more aimed at my statement in the last sentence of the above paragraph.
