If you don't mind wind check out a the Spring Creeks in Livingston this time of year. They are half priced and will be loaded with fish. Stay away from the spawners, they will be really easy spot and need to be avoided at all cost. There will be a ton of trout in the holding riffles and runs. It is a real blast.This is the best time to fish anywhere in SW Montana as there are always days that warm up to the 40's which gets the fish feeding furiously. Egg Patterns, san juan worms, wd 40's, blood midges, its all gravy. Have fun and respect the fisheries, it is real nice to go to a place where people actually respect the landowners and pick up trash even if it isnt their own. I moved here from there and miss it every day.
Fish on.
