The 2nd Worldwide SketchCrawl Day is coming up. Sunday 6th March.
Basically what you do is get your sketching kit together (in my case, sketchbook, pen, brush and water, warm coat, big scarf, furry hat and gloves, chocolate!) and you document your day as best you can using drawings.
It doesn't matter how well you can draw, it's the taking part that counts. And take it from me, it really is good fun, plus you meet people you'd never otherwise meet (great when you're usually isolated all day like me.)
So, wherever you are in the world - why not have a go.
