Will smack you in the face!
My daughter and I were fishing a private lake Friday night when the L.H.'s came in to see what we were up to. We started feeding them some range cubes and one got a little close turned his head and smacked a horn right into my girls cheek. Ouch! Luckily she is raised on the "walk it off" method of pain treatment.
Could have been worse but catching a few 10lbs cats lifted her spirits.
