Yellowstone National Park fishing licenses and regulations arrived in the shop today. If you intend to fish in the park during the Memorial Day weekend opening, the Firehole River will likely offer the best fishing, but expect company. Bring BWO and caddis life cycle patterns and small nymph patterns with and without bead heads. Some Hebgen Lake run-up rainbows remain in the Madison River after spawning. These fish will take streamer patterns swung deep, and some of the best places to encounter them will be from the Barns Holes downstream to Baker’s Hole.
