Big browns and big bass feed at night, and big Alaskan rainbows love to whack a lemming or two when they get in the water. The Mouse Fly is the ticket for both. Great realism as you swim this fly pattern across a river. Fish it near banks where the high grass grows when the wind is blowing or at night. Make sure Mouse Fly plops on the water and then swim it across. Just don't freak out when the big hit comes. In natural.
