This is a fine warmup. Put in just upstream of the Ashuelot covered bridge. The run from here is an easy class II for approximately 1.5 miles to the backwater of the first dam. There is a line across the river warning boaters to carry around a dam. Take out on river left by the sign and carry around the dam by the old factory. EDIT: The factory owner on river left doesn't want people trespassing; recommend portaging river right.
