It doesn’t matter how young or old you are. Drawing with sidewalk chalk is fun, and anyone who gives you a weird look is just jealous that they don’t have the confidence to doodle on the ground. While this artistic medium can be used to leave your mark in one place, don’t you wish that you could lay a trail of masterful pieces all over town?
While the Chalktrail does need a bike hitched to it to really be effective, this is one way to express yourself creatively and get in a little exercise. This contraption attaches to the rear axle of a bicycle, and will drag a piece of chalk on the ground behind you. You don’t need tools to put this on securely, and one piece of chalk will last you 1.5 miles. The chalk arm can either come in red or blue, and will cost you $20 (with an additional $7 for more chalk).
