The BRP is a national treasure. I have ridden every mile of the parkway, but never all in one trip. The narrative, videos, and pics did an excellent job of depicting the riding experience on the parkway. I hope to do an end to end trip someday.
What I am most impressed with, is how well the National Park Service has been able to preserve the sense of soltitude you get when riding along the parkway.
This has been a challenge I'm sure, since there a few places where encroaching civilization is just a few hundred feet from the roadway.
