Rowed this am with a mirror. A sop to old age. But it did allow me to line up on the bridges early (just looked a little, to make sure my oars cleared), scanned the bow for oncoming boats and landed better than ever. On the downside, I wound up in an overhanging tree and found myself on the wrong side of the river three times. Could have been a disaster, but it was a quiet day. Bears more practice.
