While I was tubing with the kids today, I came upon a boater that broke down. They had drifted over near shore and were paddling (in vein) to get out to deeper water. I went over to lend assistance and offered a tow to a local marina. They only wanted a tow into deeper water? Again, I said I would give a tow to a local marina or their home dock if close by. They declined with no explanation and said thanks. I'm just a little confused as to why they wanted to remain stranded? Any ideas.
