Off for the summer with my 8 year old and have intentions for a trip or two to Colorado. Still in the planning phase but here are some details so far. On a budget so can't afford to rent out a vacation condo/home for a month or more, was planning on buying an annual state park pass and camping much of the time, as well as an occasional hotel stay. Taking the tandem so much of the hills will be doable, even for an 8 year old. The main question is, what state parks have good/safe road riding access? Any other input or questions would be much appreciated.
