People actually waste their time doing this? If you really want to waste your time, go the the same "confluence" (as Dru said, really a crossing) in NAD83, WGS84 (a step away) and NAD27 (>200m away). When you get to each point, be sure to walk around, treading on as much ground as possible within an area 15 metres across; this will take into account the positional error of the GPS and increase the likelihood of stepping on the actual point. You would at least get a bit of exercise.
