The Bull Pasture and the Hidden Valley of the Jackson are producing good fishing to anglers who are using streamers that match the minnows the trout are feeding upon. Three of my favorites are the Shenandoah Silver Ghost Simple Streamer size 10, Shenandoah Midnight Simple Streamer size 10 and Mr. Rapidan Streamer size 10. Fish these flies across streams with a slow line hand stripping action.
