One little side note - Just as I picked up the PLRoad I noticed a couple ahead of me, maybe 200 to 300 yards. I'd catch up with the wife a little at a time on the uphills then drop off for one reason or another, often traffic, on the downhills. When we reached Jordan Pond House I finally caught up and we crossed over to the grounds together. We'd barely gotten off the bikes when the guy says "Wow, what a beautiful old bike!" I explained how it was a '73 and we spent the next 15 minutes taking with each other and a guide from Vermont Bicycle Tours who was waiting for his charges to arrive. It was great fun.

It turns out they were going up Cadillac too, still some miles ahead of us. I started up first, made a few stops and one longer one very near the top to eat something and admire the awesome view. As I'm eating the guy comes slowly up the hill, and about 5 minutes later as I'm getting ready to start again his wife comes along. We tagged up the remaining switchback but I had to pass her because my lower gears begged for a higher cadence. I got up to the top and started talking with the husband. When she got to the top 15 seconds later she gave us guys a fist bump and declared how good it was. She was right, it was good!

Addition: I recorded the elevation vs. time on my altimeter-watch. It reports total ascent of 3440ft.
