If so, meet me and hundreds of others this Saturday, November 6th, at 11:30 at the Toronto Zoo.  Check out their website and click on the Yo-Yo for the Do-Do link to give you all the information you need to participate, as well as informatoin on the reduced entry fees, and for all participants, a free yo-yo.   The Guinness World Record attempt is being spurred on by the Zoo's initiative to raise money and awareness of endangered animals, so not only will it be good fun, but you will also be supporting efforts to help endangered animlas and their habitats.
