Illustrator Gerry Olin Greengrass loved a parade so much she decided to create a board game to hold onto the feeling year-round. Game enthusiasts now get to join in the fun with the release of The Great Macy's Thanksgiving Day Parade Game. As in the annual Macy's march down Broadway, Santa Claus takes center stage. The player (two to four can compete) whose Santa travels the entire parade route and enters the Herald Square store first wins. Depending on the roll of the dice — and the float or balloon square landed on — game pieces move forward or loss ground. "Surprise cards" keep the action going. Greengrass enjoys playing the game with her 4-year-old grandson, but says she'll be out on the real parade route again this holiday.
