Colossalcon East

Colossalcon East is an anime and gaming convention held in Pocono Manor, Pennsylvania, USA. It's a regional sibling event under the Colossalcon umbrella, held every September at the Kalahari Resort and Convention Center - Poconos, whose ~220,000-square-foot indoor waterpark has been billed as the largest in the United States. It's known for combining con programming with the waterpark resort setting, including a scenic on-property waterfall that's become a popular cosplay photo spot.
