Do you know where to find someone nearby? Then you will be invited to “hang out” with other members present. This wat, the other members can judge whether you would fit in or not.
Do you want to become a member? Then you have to show absolute dedication. You cannot accept an invitation and then cancel it. Once you fail to show up, you can forget about attending another event later. And even once you’ve become a member, you can’t simply skip an event. The idea behind the Hells Angels is that it is a brotherhood. You don’t show up? Then that is regarded as a serious misstep that shows you don’t have respect.
