I've done the tubing thing twice.  Each time, the rocks and trees kick my a$$.  But you get nice color, or a serious burn, and if you survive it, it can be fun.  On a day when people might not venture out to the river, it's peaceful and the nature you see is plentiful.  On the Fourth of July, hang on to your hat....and pants....and tubes...and keys.  \n\nI actually held about 6 water bottles worth of liquid from point 1 to the end point 4, but most people urinate on themselves.  It's not a \"high brow\" activity, but it's an experience and the cool water vs. the hot day is a good contrast.\n\nJust remember, it's a real river with real rapids and real undertows.  You can really get hurt, even if you are a star swimmer.  Don't go it alone.\n\nIn terms of a family affair, I heard the f-bomb at least 20 times.  Most everyone was covered with tats and many were reminiscing about the time they were \"locked up\".  And the average age of people there when I visited was probably 21.  Not something I'd take junior to do.
