There was a group of 12 of us out camping.. one guy was know for sleeping in and sleeping soundly.... the first morning, the rest of us got up, quietly packed up camp, and reset up camp around the point of the lake (some 125 yards away).. we took everything including the firewood shavings and footprints. Yep, we swept the ground with some branches, clearing our path.

It took him a couple hours to figure out where we were... we never told him that we moved camp. To this day he thinks he moved in his sleep!

That beat the time we slid his dome tent down to the edge of the lake so the door of his tent about an inch from the water.
