I want to plan a one day guided drift boat trip for the end of May when my father comes out to visit. I'm in Loveland (Northern Colorado) and would like to stay within a 3-4 hour drive if possible. The only fly fishing I have done is for pan fish and bass back in the midwest. Can anybody offer any suggestions or where to look into? I've heard that up north Grey Reef has great fishing but is lacking in scenery. Would be great to have both nice scenery and good water to fish. Thanks in advance.
