It depends on what time of year you go. Stop in the town of West Yellowstone in Montana on the west side of Yellowstone Park. They have 5 good flyshops and all have info posted that they change frequently to let you know what hatches are going on & what works well. You could probably call them ahead of time as well, just do a search on Google, you should be able to come up the names. If you're going a specific time, they can tell approximately what will be hatching. If you can't find them yourself, let me know I can round some names up for you. We just came back yesterday from a week of fishing up in that area. The best fishing right now is on the Madison River below the dam of Hebgen Lake, just 15 miles west of the park.

#2 Long arming...
