There's a few furry events in my city which are basically "This pub, this day of the week every week". You don't bother working out who is going, how it fits in to everyones schedule. You just go if you feel like doing something that night and there will be people there.

I've got a few friends who I don't even have the contact details for, If I want to talk to them I just go out to whatever the current event or party is and they will probably be there.
