I'm planning a 2-3 week trip next summer (2018) in Colorado. We prefer State Parks as they have hookups, bigger sites and showers! I thought by planning THIS summer, I'd be able to reserve - however all the state parks are showing completely booked for next summer. Are they just not taking reservations yet - or do you have to book 2 years out for these spots? It's frustrating to finally have our camper, and not be able to use it the way we want to. We're constantly dealing with full parks everywhere - even in our home state (Illinois!).
