South of Roosevelt Academy is an elevated railway track. Follow alongside it heading east until you see an explosive chain of cars ending in a bus. Hop down into the valley where the highway breaks off and a red train car has collapsed. Go down the valley a short distance northwest, and you will see a raised wooden platform on your left, which appears to be his/her camp. The wanderer will be patrolling around this area, accompanied by three raider guard dogs. See the images below.
