Why "Pin" Mill? I don't know. It's on the coast, on the Orwell estuary, just outside the large village of Chelmondiston. You can approach it by a narrow road, but I approach by foot through dense woodland along a ridge overlooking the estuary. As you descend you come to a series of houseboats, all with names, many with postboxes and with wooden walkways out to the boat, with plants in pots and other decorations plus various junk. Some are quite neat and others very dilapidated, plus the occasional rotting ruin.
Beyond the houseboats the path suddenly comes out to a small bay and to a concrete surface sometimes under shallow water, but usually merely damp. To the right are moored yachts, motor-boats and rowing-boats. To the left is a large pub against whose solid walls high tides lap - "The Butt and Oyster", which must amuse visiting Americans. It's an Adnams' pub which means decent real ale.
Beyond that, a road and a shambles of interesting buildings, workshops and the like, then a few brick houses, a marina office and more woodland. People come to the pub to eat or socialise and drink and the place attracts some day-trippers, maybe a few genuine tourists and of course people off the boats, but a proportion of the people walking around or driving vehicles very short distances are roughly dressed, long-haired, weatherbeaten men. I know few places quirkier or beter to rest on a long walk.
