By order of* the New Braunfels' City Council:No containers under 5 fluid ounces are permitted. (This usually refers to*"Jello Shots"*in 5 oz. or smaller containers. This rule was created because so many people littered the rivers with small plastic containers after shooting down their Jello Shots, causing environmental problems. Jello Shots have NOT been outlawed, only containers that are 5 ounces or smaller have been banned. You can still bring your Jello Shots in containers larger that 5 ounces.) Please Drink responsibly, thank you!*
