Some folks need or appreciate 'structure and/or acceptance'. Some may find it in MC clubs, especially if the club is '~similar~' to their lifestyle.
Strikes me even more odd that anyone not involved in a 'traditional MC club" would ever 'dress up' to look the part,,, Too much 'Sons of Anarchy' I guess.
Always get a chuckle when 'Chibbs' or some other SOA actor is a 'Special Guest' at any MC event.
Men and women alike line up for autographs,,, Some things I just can't explain,,,,
