It unfortunately didn't go very well because we were afraid we'd get in trouble if we actually drew a rose on North with chalk. Instead we made a mural of a ChalkRose and taped it up where the rose had been. Sadly, we did not use enough tape.
We did, however, leave a bag of sour gummy worms for Jared because he hates chalk.
People involved: RachelGabor, MaryPeter, FessNelson, and definitely others, but I forget who.
