That's what I used to catch two trout on the upper Patuxent yesterday. Started the day going downstream from Howard's Chapel Road, but got caught in the rain without my rain gear. Walked back to the car to get the rain gear and eat lunch and decided to drive further upstream to Hipsley Mill Road. Both fish were brown trout, one six and the other nine inches long.
Water level was 2.5 at the Unity measuring station.
