Just got back from an awesome trip to Marble Canyon, AZ. A good friend is a guide for Lee's Ferry Anglers and I went down for 4 days. The Colorado is an amazing river to be on below Glen Canyon Dam, and the trout though not huge, are big fighters. It's an incredible area to even see, vermillion cliffs, condors, anyone who would like to go down this summer should. Terry Gunn owns the fly shop/guide service and lodge where I stayed. Great people too! I'm headed back down in 2 weeks for more.
