Floating down the Tube Chute is fun. It is best to bring some water shoes and a life jacket, but a tube is optional. I usually do it a couple of times during the week (Mon-Thur) without a tube, usually starting at 7pm, when they stop charging for parking or admission. Going before 7pm means you have to be ready to endure rules and stern looks from those that work there, and you have to pay $21 to park and pay about $6 per person to be able to get out of the water and walk back to the top of the Tube Chute. They lock the gates Fri-Sun at 7pm in the Summer. The stated reason from workers that would provide an answer as to why the gates are locked just evenings a week said it was because fights have broken out after hours on a weekend.
