As I'm sure SBC can confirm, over here on the east side shrimp are probably the main bait (if not a close second) for people fishing from the bank on our rivers (Snake, Clearwater, ID. Grande Rhonde etc). Almost all of the grocery stores and tackle shops even sell specially packaged "not for human consumption 'bait shrimp". The majority of the people here use shrimp under a bobber with a marabou or bucktail jig or just plain hook. But shrimp certainly work well on a drift fishing outfit as well. I always dye the shrimp I use with just a little red food coloring. I too have had great success using this method but I always have some good eggs ready if thats what the fish are willing to bite. Gotta be versatile to be consistent!
