26-Mar-2006 -- The Great Adventure – Stage Eight

- A proposed trip to Mankato, Minnesota to work with three groups named Kids Against Hunger, with Outreach Africa, and Life Tracks which are non profit groups that help disadvantaged groups around the world, sparked my interest in seeing if I could hit a bunch of confluences while on the trip.

After checking GoogleEarth it looked very possible with one minor problem, most would be latitude changes. In this area the distance between latitude change confluences is about 69 miles.

The total round trip was accomplished in 5 days and a total of 11 confluences. Two of the days had 5 confluences visited on each of the days. The trip included 34N 97W, 35N 97W, 36N 97W, 37N 97W, 38N 97W, 44N 94N, 42N 93W, 42N 94W, 41N 94W, 41N 95W, AND 40N 95W.

Another location in the middle of a field. This one was not so bad since the sun had been out for a few days and the surface was reasonably dry.

One thing that was interesting to notice here was that all survey points are the same. It appeared that the field was divided along survey lines which did not exactly match up with what I was finding. Did the farmer not plow all of his land or did the other farmer plant more than his land?

Great Adventure Stage Eight complete. Now on to 41N 94W
