When I was in college, we played the Yankees in the 1999 World Series. Some boys who lived in the apartments across from me carved up a Yankees pumpkin (like this, but not that good, haha) and I came home one day to a Braves rivalry pumpkin on my front step! That was awesome.
Well, if you'd like to make your own Braves pumpkin, the official website has some stencils you can use. If you make one, please send me a picture and I'll post it! :)
PS -- Thanks to Crista for the link.
PPS -- The night the Yankees swept the Braves, the boys walked over to my front porch, blew out the candle in the Braves pumpkin, waved at me through the picture window, high-fived, and ran back to their place. Boys are stupid. (But fun!) :)
