I've done this for quite a few years, but now that I have gotten older (I'll turn 67 on Weds) and have high blood pressure, which is under control with meds, and back and shoulder pain issues, my wife doesn't like me going out, especially alone which I did all the time until the last couple of years. Fishing from a float tube is just so much fun. Good exercise too, kicking around with swim fins on my feet. I do have a floatation vest that is required, but in the summer I just tie it to my 'tube. In the cooler months I'll wear it along with neoprene chest high waders which help keep you a bit warm from the cold water. But since this is Southern California, the lake only gets down to about 55 degrees or so. Does anyone else out there go float tubing?
