A challenge

[Cormanus]

I think these guys probably used a GPS app that plots where they actually went—you can get one from Navionics and put it on your iPhone. It's free I think. You fire it up when you start out and it tracks your every turn. I'd use it all the time if I could easily find a way to transfer the data to Google Maps.

So, someone has to work out a route that will result in the GPS track drawing a CB1100DLX.
