Went there Sunday at 1 p.m. and were turned away--told the river is too shallow to make the 2 hour trip before closing.  Hmm, just had record rainfall, busloads of people returning from tubing, river looks as deep as I've ever seen it.  Not a good way to treat customers.  Update your website if you're going to pull this sort of thing.  Have been here before and had great time; not sure what's up with this business now.  They WERE selling bus rides to people who brought their own tubes.  Odd.
