Source : Chalktrail Tell me more Chalktrail is a super cool way to combine a little bit of art with physical activity. It's a simple device that attaches (no tools required!) to your bike or scooter along with a big piece of chalk so your kid can chart their path and create "art". The road they travel on becomes their canvas. The chalk lasts up to to 1 1/2 miles, which is good bang for your buck at $6.95/4 pack. The device is $19.95. [db:qq]
