Diamond lake is apparently good fishing. Monday morning there were at least a 100 boats on the water by 6.30AM. To put it in perspective the path around the lake is 11 miles. I haven't seen one guide though? Why, to easy to just get out and figure it out?
Later this summer I'll visit one of my groomsmen Ron who is a professional guide in Yellowstone and Argentina. I think he does pretty well for himself, especially doing something he loves. I don't know a ton about fly fishing but I believe there is a lot more technique and local knowledge required to be successful- key ingredients for any business.
