Thanks, Jim. Ummmm, maybe: I tried to check a couple of 14% grades, both up & down, which I know in the Madawaska Highlands. Your note on using the "directions" icon & the bike helped, but the drill proved to unsatisfactory (as I find Google's new map formats generally): Wretched thing wanted to redirect me to a route I didn't want (jeez, there aren't many roads there, after all!) and, once I did persuade it to blue-highlight *my* route, the thing wouldn't remain visible on the map. Piqued, no doubt, by my stubborn desire to ride clockwise, so's to have the Wind At My Back going up the 14-per-centers. (Doesn't Google know anything about prevailing winds??)
So -- good idea, lousy execution, here, anyway: 2.2 / 10 No point complaining to Google though -- try, & you get sent to a Forum where hundreds of lost and frustrated souls seek Explanations For The Unexplained. Reckon I'll stay with my archaic but wirebound & nicely topographically shaded "Eastern Ontario Backroad Mapbook"; and trust to Osi's trick new low-low gears to get me up whatever lies ahead. :-)
