Either I did something wrong or this is a bug of sorts.
I re-entered (or actually changed the route name in my log) for Grand Loop Road around Yellowstone Park. On our 2000 vacation, we came in from the east side and went counterclockwise to Montana, then hit the southwest part of the loop to leave through Teton.
But when I plugged the line in as "EEntRd SEntRd", the route was filled in only in the SOUTHEAST quadrant - i.e. the very segment NOT traveled!
I think the issue is that the "loop" starts at the north entrance. Does that mean, to make it run correctly, I need a double entry with one line being "NEntRd_E EEntRd" and the other to read "NEntRd_W SEntRd"?
