Zero information about terrain online that I can see. Bayesian updating: it's full of green and not that interesting technically. Correct?
No, we're just bad at posting content. High Rock - or the F. Gilbert Hills State Forest - has generally open woods with comparatively few pokey-stabby plants. The trail network is somewhat dense, but the woods are very runnable. We expect pretty good visibility. It has excellent vegetation given that it's near Boston. The terrain is pretty similar to both the Blue Hills and Blue Mountain in New York - lots of rock. The biggest deviation from white woods are areas with knee-high blueberry bushes, but even they are a minority.
This event will be fun for everyone but economists, who will gain utility compared to not coming.
