So not the reason I would have liked to plan a trip to Montana or the time I'd prefer to go see the state, but anyway my sister in law is getting married in Big Sky in July. My family will be out there for 5 days, I have one day to play/fly fish. The problem is that the guiding services that are recommended by the lodge we are staying at requires children be 11 or older. My two sons will be 9 and 4. One guide offers a family fishing session at one of their ponds. The cost to me seem pretty hefty for 4 people to fish for 2 hours, but it includes all the gear we need and no need to purchase out of state fishing license for the 1 day I'll have time to fish. Any one familiar with this area? Or could point me in the direction of a reputable guiding service?
