As someone who experienced some summers of love : Those being from 1988 to 1998!), I became aware of the terms "New Age Wanderers" & The Clubbing Tribes, a bunch of people with no gender specifics who cared about one another and protected each other from getting hurt whether it was through Booze or whatever, we offered each other shelter whenever we travelled, and you could be certain that even if you popped into a city unannounced you had a roof over your head and aplace to crash, nearly everything was shared.
That to me is a tribe, people who nurture and care for one another, who love each other with no regrad for class, creed or colour systems. People who protect you and nurse you back to health one your lover has left you died or whatever, the ones when you phone them say leave now come to us we will help you get over your troubles, find you work, make you forget if only for a little while.
