I work for a shop near the upper CO in grand county. I see a lot of guides on the water from summit county. the crew from breck outfitters are top notch.
The ‘other shop’ has some good guides as well. but, a reputation for being snotty toward customers @ times. If you do book a trip through them, request shane. He’s a good guy and good guide. If you think you might end up fishing the colorado in grand county, I’ll be glad to offer suggestions on access etc..
