RedBone considers learning to run a speck, specklebelly, snow goose, blue goose, Ross goose, cackler goose and sandhill crane call as being the same as learning to play a musical instrument. Get a good instrument, get good instruction and practice. That is the idea behind RedBone. RedBones have been used successfully in 12 of the last 14 World Championships.
