Also out on the river today was Jeff in his Czech built Zastera racing kayak. At least, I believe it was him I saw heading into the Assabet River near Egg Rock. And at Great Meadows Landing, I encountered a terrestrial patrol in the form of an electric powered vehicle. The vehicles pilot, Alan of Bedford, stopped briefly to chat, before resuming his patrol down the trail. Great Meadows Landing was also my turnaround point for today's patrol.
