steel rusts pretty much everywhere but being so close to the sea it rusts faster than normal. normally that's not a good thing unless you're looking for photo opportunities. then suddenly it's a good thing. luckily it's not hard to find, especially in the park that was a naval base back in the days of wooden sailing ships. there are plenty of historic remnants lying about and many of them have at least some steel.
i took all of these photos with my S22 phone camera
