I love to hunt hard hit camps for hut sites.. When you get into a large hit camp and see there is been no or maybe only 1 or 2 hut sites dug and you can tell it's only been free roamed you know your in for a good time, dont ever give up until you dug out any possible hut or trash pit, the deeper you go down (2-4 feet) the better in the huts and pits, it can be very frustrating sometimes but the moment you find you're first hut or pit and dig a load of relics your gonna be hooked.. Remember all the soldiers in camps had to throw there trash away into a pit.. Good luck I bet you there is some awesome finds in that spot you're hunting just gotta get deeper!
