MCR4 is a dinner at the Rubicon Springs. It's not a trail run where we lead a group through the trail. So we won't be inspecting rigs. We will meet everyone at Rubicon Springs Saturday afternoon/evening. I would strongly recommend having a parking brake of some kind on your rig. Too many people have been killed and too many truck have been totaled as a result of not having a parking brake. If you don't have one, install one before you come or leave your truck at home.
