Watermelon Days, World's Largest Watermelon
Green River, Utah
The giant watermelon slice is 25 feet long, built in the 1950s to take part in the town's Watermelon Days festival, which is held every mid-September. It is reportedly the final watermelon festival on America's yearly watermelon festival calendar.
The slice was motorized for a time (it's hollow, on a wheeled platform, and has a door in its side), but the engine is broken and it has never been repaired. Now the slice is towed around town, but that doesn't make it any less impressive.
