I visited San Francisco in October and there must have been something going on in the city because many hotels were booked up or exorbitantly expensive. I retreated down the bay and stayed at Hotel Aloft near the San Francisco Airport (SFO). It turns out that the hotel is just a short walk from Bayfront Park and I took the opportunity to do a late afternoon stroll in the area.
I crossed this small footbridge and found myself walking along the San Francisco Bay. The tide was out so the scene was all rippled sand.
Small channels snaked their way from inland out to the Bay.
