It's easy for folks to complain about what they don't understand. It gets a lot harder to complain when they find out just how much work is involved in getting a wildlife area ready for the fall, or better yet, for the reproduction season. If the area is diverse in various habitats, there is less of a chance for the manager having an "off" season. What is normal is having a variety of demands on one's time at the same time. Training, meetings, open seasons, law enforcement, beaver problems, burn season, and opening the campground all fall at the same time and the manager has to prioritize getting the most important work done first and fitting in the other tasks as time allows. If a crew showed up and eliminated some of those, the manager could do a better job on the remaining shorter list. The largely unknown secret of managing a wildlife area is that, if we didn't have to fix things that visitors damage unnecessarily, we could get a lot more projects done that might improve the area's ability to produce wildlife. Rutted roads, cut fences, pulled down signs, trash, and vandalism all take away from habitat work. In Kansas, we average 7000 acres per public land division employee. Check with any farmer and he'll/she'll tell you that is a big chunk. I doubt Wisconsin is much different.
