The rest of the Hemlock Trail led me back along the shore of the Upper Hemlock Lake . . .
past some lovely mountain laurel . . .
and the remnants of a quintessentially New England-style rock fence.
I'll have to admit being a little mystified by these letters I found along the Highland Lake Trail. Turns out, NEMBA stands for the New England Mountain Bike Association, whose members, I presume, help maintain the trail.
