Also, the loons and geese are migrating, and I paddled through a mixed flock of 75 or so. A pair of swans were gliding along as well, with their tail feathers rigged up as sails.
I took my handheld GPS along. Including halts for rest or sightseeing, I averaged 2 knots. "Cruising speed" is in the neighbourhood of 2.5 to 2.7; putting my hips into my stroke and carrying it farther aft gives me 3 knots with a bit of effort but not too much. My absolute top speed was 3.5 knots, with much churning of water behind and at the forefoot.
