These tubes reminded me of big black flowers as people carried them up the road. The Deep Creek area of the park is popular for groups wanting to tube in the creek. Businesses rent tubes just outside the park entrance. Tubers have to be willing to schlep their tubes a mile or so up the trail to get a ride. It looked like fun when they were bouncing along down the river! It might look "geeky", but people would be well advised to wear helmets, shoes, and even knee and elbow pads while tubing, it could help save them from serious injury.
