I'll be in Fairbanks during the first week of June for a class at UAF, and I figure in the evenings I'd like to explore the local waters with fly rod in hand if at all possible. I know there are grayling in the Chena, but that's where my knowledge of Fairbanks-area fishing ends. Is there a stretch of water that I could float in my packraft in ~2 hours where I'd be able to cast to a few grayling with road access on both ends? I envision locking my bike to a tree, driving upstream and floating back down while fishing, then biking back to my truck. Is that idea feasible? Any other suggestions?
