Labor Day weekend is often the last chance families and friends have to go camping before the leaves start turning and the nights get cold. At the US Army Corps of Engineers campgrounds at Lake Red Rock, Operations Manager Josh Conrad says all their reservable sites are booked this weekend. He says they still had some sites available this morning that were first-come, first-served. He recommends calling the main office to check on their availability before driving to claim them. That number is 628-8690.
