It's great fun catching bull frogs on flies at night. You go out after dark with flashlights or headlamps, a 9-10ft cane pole with a length of mono and a big dry fly attached. When you spot a frogs eyes shining back at you, you reach out with you pole and dangle the fly close enough so the frog will get it! man they sure can fight on a light cane pole. We used to get'em in the irrigation ditches, in the late spring when I lived in Klamath Falls, OR.
