Thanks in advance for the input...<br /><br />The kids are finally getting old enough for a tow tube. 7 and 5 y/o, I am looking to get a suitable tube to take them for a nice safe, slow ride. Those of you with experience, what size and style tube would work best? I doubt we will be pulling adults, certainly not me. (unless they have a new submarine model designed do go under) Are particular brands better? Where to buy? Does a large tube tend to go airborne w/o sufficient weight?<br /><br />Thanks,<br /><br />jocko
