Inner tubing
A person engaged in tubing (or "inner tubing"), the recreational activity of riding an inner tube, either on water, snow, or through the air. Tubing on water generally consists of two forms: free-floating and towed (shown here). In the latter, one or more riders tether their tubes to a powered watercraft, which tows them along the surface of the water.Photo: Peter Opatrny
