I hope you've noticed that we have put a basket of sidewalk chalk out in front of the library to encourage all of you to be creative and leave your mark. We've had some beautiful art show up already. If you want a lasting creation (well, it'll last for a few weeks anyway) draw under the portico. But, if you are the type that enjoys the transience of beauty, then draw on the part of the sidewalk that is not covered; when the rain wipes away your art, draw something new.
To see some AMAZING sidewalk chalk art...and I mean AMAZING...check out street artist Julian Beever (this is a clickable link).
