Wow, TFC, I see what you mean!

I think, though, it is a function of all the way points you have in your file. Each one shows up as a little circle, so on the map that shows the entire loop, they are huge.

I went to your map, switched to satellite view, and then zoomed in all the way, and your route looks ok. ...but then I see you have a waypoint about every 50 ft!

Maybe Joseph can give us some hints.
