I used to ride Jackson in high school and never had any problems (and did some stupid stuff) but that was 10 years ago. Up here the DNR, from what I understand, can technically give you a ticket if your pump intentionally leaves the water . It really depends on the DNR officer and how busy the lake is that day from my experiences. I have had them come up to me and pester me even though I was riding completely legal (100 feet away, registered, etc) but right next to a no wake zone...Busy day they didn't want me run over I guess... I usually just joke around with them and ask them how I can get a job with a boat and a gun... Other days i'll nose stab off their wake and they give me a thumbs up. I even pointed out some stupid couchers to the DNR one day and they went and pulled them over... I always wear my helmet and stay 100 feet away from the boats when jumping their wakes. Been riding for years now and no ticket yet, knock on wood.
If you get stopped. Be respectful and at least act understanding. If unsure about something just go ask them for clarification on the law... Funny when you get 2 different answers and the officers start trying to figure it out

Let them get to know you on your lake. Once they know you are and out there all the time and not just some weekend warrior, they leave you alone from my experience.
**edit, from my understanding jackson lake was empty the past couple years from damn repairs. They are probably hurting for funds if they are writing tickets like crazy.
