After breakfast, I fixed my rear tyre puncture and switched around the front and rear tyres - the back tyre needs to be the bigger gauge (28mm) and the front (less load bearing) the smaller (25mm). Then we packed and went to the bookshops in Anacortes - in particular Pelican Books' which is a huge secondhand (or in American, used) bookshop. I bought 'Close Range - Wyoming Tales' by Annie Proulx, more exploration of modern American lives, and would have bought more but I know we are very close to our luggage limit on the flight home. Perhaps some items - inner tubes and socks and books (if not good enough) for example - may be abandoned before we fly. Then we headed around the peninsula to Deception Pass, about 20 miles altogether, and so named because the explorer Vancouver thought this was one long peninsula but it is actually several islands, with some alarming currents between them - as we saw from the Deception Pass bridges - see photo - a current of 8 knots pushes through the gap between the islands, with whirlpools, rapids, standing waves and very variable depth. It is a bank holiday weekend here in the USA and the area is crowded with heavy traffic. This is no place for a quiet bike ride or a safe swim - just here. Once we had found a hiker / biker tent space - no other hiker / bikers here at the moment, and found somewhere to charge this phone I type on - threatening to run out of electricity - we visited the beach. It has a great view over islands and promontories, running out into Puget Sound. I swam but stayed in the shallows, within three feet of water. The water is cold and clear - something like an April swim in Pembrokeshire. Very few people were swimming - after a minute my skin was going numb. Further out the water looked disturbed by currents - a whirlpool near some offshore rocks. A place to play it very safe. But a lovely place to sunbathe and a lake behind the beach offers much warmer and safer swimming - nicely buoyed areas showing where to swim. But salty water is a bit more magical. There are killer whales - orcas - in these waters and so yet more reasons to swim in the shallows or the lake. It is very impressive but we are a long way from a decent grocery shop and we want to get more views over the islands so we'll be cycling to scenic points tomorrow.. We are here. The hiker / biker area is now pretty full...
