Waterside A from the air
I had an idea that it might be worthwhile checking out D-W portages with Google Earth to try and gain some familiarity with the course.
My first experiment was to create this Tour, a virtual fly-by of the Waterside A course we paddled on Sunday, showing all 17 portages (right click to download the Google Earth .kmz file, double click and it will open open in GE - don't have GE? Shame on you. Go get it).
Luckily, almost the entire D-W course, except the first few miles from Devizes, is covered by high resoloution imagery so this may prove a useful (and certainly fun) tool.
