I will respond to this before it gets too far out of hand. I think I have authority to do so from a couple of angles. I will go through what happened here in chronological order:
First I worked with Dane County Parks to get this property acquired for the park. I then worked for seven years on developing the Master Plan for this park and getting it approved through public hearings, board meetings, etc. The Master Plan now defines CamRock Parks as primarily a recreation park. Some ares are designated as suitable for prairie restoration, both upland and lowland, and some areas for Oak Savannah restoration. Only some of this work has been done as the "Friends of CamRock Park" is a splintered and disorganized group. In the early years CORP put in 10 times the work toward these efforts as the Friends group did. These days the Friends primarily work on water monitoring of the creek. Other individuals are working on restoring the Oak Savannah's, which we see on our trails. There is not an organized effort of restoration in the park as there is not an organized group to lead it.
But I digress. Following approval of the Master Plan, I was then the one who initially laid out the bike trail through this area, an old soybean field, once getting approval from Dane County Parks. Then the trail was constructed in 2007. This was the very first sanctioned activity on this property after it was acquired. Then I was a member of the group that did the restoration of the prairie. And I have to say, restoring prairie is held in such high esteem, and I really enjoy the prairies myself, but that is easy work compared to building and maintaining a bike trail! We mowed the weeds down. Spread some expensive prairie seed over the snow in the winter. And viola, prairie!
And for two years I have been the one pushing to get the highly eroded, rutted, and unsustainable trail reconstructed into a sustainable trail.
Yes the "bumps" as you call them serve a purpose for trail sustainability. Yes the trail needed to be re-routed in order to make it as sustainable as possible. Yes we scarified the old trail and spread some more of that expensive prairie seed in the old trail bed to restore those areas.
Believe it or not this is one of the hardest areas of the park to build a sustainable trail. It is basically too flat. And if that does not make sense then I recommend the great book put out by IMBA called "Trail Solutions: IMBA's Guide to Building Sweet Singletrack". It is 272 ages of what it takes to properly design, build, and maintain sustainable singletrack mountain bike trails.
So basically what I am saying is that as a person who both built the initial trail and then worked on the restoration, nothing was done lightly. It needed to be done and was done with a purpose. If you want to get involved in those decisions the opportunities are there. And if you have the passion, there are many more opportunities to restore more of that beautiful prairie in the park. Like the new area you mentioned with the berms and rollers.
But from my opinion I don't think once an area is restored that makes it sacred. It can be modified. It can be moved. Just like it was created more can be created.
