I was spinning at a local craft fair over the weekend, we had two official slots in the demonstration area and we took it in turns to spin beside our stand as well. It was very busy and it was inside, so nice and warm!
Next venue though will be on Castle St, off Princess Street in Edinburgh. In a marquee in late November, argh. It will be cold and definitely damp even if it isn't raining. Good thing spinners always have plenty of wooly things to wear. I'd definitely prefer nice crisp snow even if it was colder. Damp isn't very good for wheels.
