At KK there are some angled small rollers that are there to collect water and divert it off the multitrac. They are on the one down hill (ish) section heading west for the bridge.
They seem to be getting larger...They still perform their primary function, drainage
, but they have been noticed by other users too and if you are going to do more than roll them, do so in a controlled manner and give way to dog walkers etc.
We (CAMBr) have had permission to do maintenance in KK for only a short while now and we want to keep MTBers in the good books with Naperville parks.
I hope I don't sound like an old fart
I want KK to get better and be more fun for all, so just respect the trails and other users.
If asked by the park district I will tell them as much as I know, (in bold) and don't be too supprised if they get shaved down (by the parks people) to original size again.
