Thank you all for your input.
The original complaints were that the course wasn't marked and fisherman were catching lures, etc...
When asked to keep the course up, we complied. More complaints after that. Of course, there were complaints that people could see the course when it is submerged.
This year we proposed a compromise. Keep the course up early and late season to accommodate the fisherman so they can navigate around it. We did, however, ask to be able to submerge it on weekends (in July) when there is little fishing pressure and the traffic is the greatest (tubers, etc...) to alleviate some of the damage to the course and so that other boaters feel free to boat in that are of the lake, etc...
Unfortunately, the president of the lake association, from what I hear, is opposed to the course. We'll see why in two weeks.
@Deanoski What happened that you lost your course after 35 years?
