Last June, my good buddy Mark Wizeman and I had the opportunity to truck across western Montana for a week with one objective: fly fish a different river every day with no guides or float-boat for only $150 per man per day. But as it goes, fishing is only part of the fun. You meet interesting people. End up in interesting situations, and above all else, learn how tight you really are with your buddy. Should you follow in our footsteps, here's some rules that are guaranteed to catch you more fish, keep you out of trouble, and make sure you and your friend remain on speaking terms.
