Next ones are OBVIOUS and there's a run of a few parks all at once - I couldn't make these photos anon cos they were too busy, so I'm just giving you the text description:
- Parliament Square. Maybe technically a park but more often a gathering place for tourists who will crash into you because they're too busy looking at Big Ben to watch where they're going, and protesters who I make a point of either cheering or booing depending on what they're saying.
