Great post cliff!
Riverside is in desperate need of some help. I was fortunate to play the Greater Portland Open in 05 - not sure if this tournament is still around it was part of the old New England Pro Tour/Cleveland Tour (many different names/sponsors). They had the greens running smooth and pure. The fairways were a struggle, the rough was weak, and the bunkers were penalizing due to their conditions, not by design.
When I learned that this course was a Stiles, I could not believe it. Harris is right in saying that the bunkering no longer reflects Stiles's vision of the property. With that said though, there are a number of great holes still routed, with their original green sites. I'm guessing some of these as original sites, as they are incredible unique and well built, and thought out sites. Their best green sites, really do rival the best in New England. But some have also been lost, or plowed.
Riverside does have some great holes, and a restoration would really help bring this course back to life, and where it once was. Wayne Stiles would be happy with Harris's golf's work.
I also played Penobscot Valley, in 2008 in College. This course rules. Its not long, so you can really light it up if you play smart. But you can also fire a million if you start to struggle. The greens are still difficult to read and play, and the green sites are super. I am not sure if Harris had begun their restoration before I had played there. My guess is not, the bunkers were still in dispair, bad sand, and the shaping had begun to erode. If you ever have the chance, play this hidden gem
