Poole quay bike nights great, though rammed when it super sunny and I'm pretty sure no matter which direction you approach from, the ride there is crap
Personally I think the south could do with a new meet up spot, or at least a couple more ride outs. All the awesome ones seem to be north! Mind you everythings north from me... Except Cornwall.
But a meeting place somewhere central enough that it's not too far from either the east or west I think would be a good idea. That's actually nice to ride out too!
Plan your rideouts and meets here
