Air Force Ski Tube from Sports Stuff

I know this is not meant for fishing but I have a ski tube availabe for sale.  The tube is a AirForce tube from Sports stuff.  I paid over $150.00 for it and I am only asking for $50.00.  Tubes like these are expensive so this is a good price.  There are no leaks.  This tube has stayed inflated for awhile now since taking the photo and is still firm.  There has been no air loss whatsoever.  We have taken it with us on our many trips to the lake for a day of boating and fishing.  We fish in the mornig, tube in the afternoon and fish again in the late afternoon to evening.  It is actually nice to fish off of.  We have anchored in deeper water and just sat down on the tube with rod in hand to fish.  The tube allows you to get about 50 ft from the boat with the tow rope.  It is not the typical way I fish.  Sometimes though, it was nice on a hot day to just sli[p off the tube into the water to cool down.
