Ahh, Modoc at autumn 2009 - the coolest place in FOnline ever. I was "camping" there so many times with bare fists, then hunting rifle.... It was the only "unguarded" place I know where lots of people were regularly gathering. There was lot of fighting - both single pk's, small groups or whole gangs around - and some nice roleplaying too. Unfortunately due to big changes in game mechanics and people sticking to big alliances Modoc was deserted since next wipe.
Here two screenshots from early and late modoc militia time:
