RE: 20 yard mental barrier
Been stump shooting since I was 3 years old tagging along with dads and his buddy's. Like LBR said a tuff of grass, rotten stump, leaves, clump of dirt anything that sticks out is something you can shoot at. Its the best practice one can get and boy is it fun to do! Make sure you have some sort of blunt on the end your arrow. If your shooting with field tips expect them to go by by being you won't find them nearly as easy.
