Good, 4.4 mile non-technical ride for family of five (girls 7, 9, 11). Nice scenery. We saw ducks, wild turkeys, beaver lodges.

Was a nice trail for myself a beginner in hiking. Found it a little hard to know where to start the trail and didn’t find it well marked. But was a great trail otherwise. Enjoyed the lake and nature.

Sunny afternoon, 32degrees; not much wildlife this afternoon. Wide trail, passed 3 hikers, 1 bicyclist. Great sights along the way; bunkers, water features, tri-town marker on Tri-Town Trail; recent beaver work along northern end of Harry's Way. Beautiful weather, mostly flat. Definitely easy, and much more interesting than I anticipated. Thanks for listing the trail & my pics.
