I wimped out this morning - cold & pouring rain - but yesterday I strapped on my Garmin Forerunner for the ride home and found it was about 4km longer than I had estimated....
Seeing the ride on google earth confirmed that there is a more direct route but the section of Fisher that runs through the Experimental Farm (yes - we have a farm in the middle of suburbia in Ottawa) is narrow and very high traffic volume.
With the rain & poor visibility yesterday I was surprised to get a compliment from a motorist for being visible (I have a 2w PB Blaze & Superflash that I use pretty much all the time)
