More like some kids squabbles than gang fights.
I think during your time gang fights were very
organised.Two rival gangs would go up a hill with their
assorted weapon of choice to sort things out.
During my time,we would fix time and place more like a show of
force to see who got more people,weapons limited.
Now, I think a gang fight could happen just about anywhere
anytime where there are a group of teenage school dropouts with
nothing to do.
