Hello I have an old 1996 GTI that runs real well and I'm looking to pull the grandkids behind it on tubes. I'm looking for any advice when it comes to securing the tow rope so it doesn't get sucked in, how many people I can have on a tube at a time with an observer and myself on the jetski , I live in Wisconsin and I looked at the boater laws and they seem vague. I know I can call the DNR tomorrow just wondering if anybody knows ahead of time. Thanks for any input and advice Randy
