Update on this general area, seeing as how tomorrow (Sun 30 March) is likely going to be my first ride of the year and it wouldn't surprise me if others do the same ...
The roads have taken a beating this winter. In addition to the sand and melt-water all over the place, there are some spots where the pavement has heaved, creating enormous dips and bumps that could really do some damage if hit at speed.
I did a scouting run in my car today. If you are northbound on Mississauga Road towards the forks, it is very rippled between Olde Base Line (flashing-light intersection) and the gentle left as you go into Belfountain. Start watching out for ripples as you pass Olde Base Line. Really watch out, and slow down if you don't have dirt-bike or motard long-travel suspension, as you pass the white church on the left. The worst of it is over with when you crest the hill that goes down towards the village, but there is one more nasty spot (the only one that is marked!) right near the 50 speed limit sign.
Going the other way, there's a section of ripples as the road straightens out coming out of the village, then the really bad spot is between the top of the next big hill and the white church. There are more ripples after that, but they aren't quite as rough.
Oddly, in both directions, there is no "bump" sign until well after you are through the worst part of it. "Oh. Bump! That's what all that was. Thanks for letting me know."
