Curious things, car boot sales. Some people are just trying to shift some accumulated trash and make a few pennies for it, some are trying to run it as a business, some are "proper" traders who just use it as one of many outlets. Some visitors are there for a wander, some to find bargains, some are looking for something specific.
I took quite a lot of pictures, but these are the only 2 I was happy with. I need more practice at taking pictures in such places, with lots of people around.
