if you're on an unimproved campsite the cost is $15 per night (per campsite, for up to three people). I slept in the back of a deuce on a GI cot before - if you plan to take this route, bring a sleeping bag as Georgia nights can get chilly. That would save $160 in lodging. And you'll get change from the $50 on the meal ticket (at least $4, more if you plan to skip some meals). The hardball convoy lunch should not cost over $20 per person, probably much less, depending on your appetite. There are ways to cut corners, including manning the COMMs.
