The wife and I made it to Yellowstone on June 3rd. Only got to fish a couple hours the 4 days we were there. Fished the Madison just downstream of Madison Campground, caught 2 rainbows, 14 & 18 on a yellow stonefly. All the rivers in the park were completely blown out. The fish are hiding under the grassy banks, I actually had to walk downstream to cast back up and only about 18" out from the bank. Talked to several others and only heard of a few other fish being caught. Snow storms kind of put a hault to everything as only two roads were open in the park. All in all it was a good trip despite the lack of fishing.
