Version 4 - July 5, 2006 @ 15:00

Use the southern half of map 137 only. Treat Grid Line Northing 80 as the edge of the map.

The end of each section is NOT the beginning of the next - take the shortest route between.

For Route Checks requiring a Map Reference (MR), provide a 6-figure reference with 1/4, 1/2, 3/4 as necessary. Tolerance allowed plus or minus 1/4.
