(LOTR: ROTK) Question about the Beacons.

So do those guys live at their posts, or is it a six month posting, or what? One of the beacons is just sitting on top of a mountain, it must take an enormous amount of resources/money to keep those things manned.

Sentries likely spend a few weeks at a time stationed. It's not that expensive to maintain actually, since it only requires that the wood for the fires stays relatively dry and some food for the sentries. There is trade between nations, so fresh guards can simply ride along with a caravan and head up the mountain when their shift is due.
