Combining Interrupted Marks, Ydrill, + 7 Bumper Lining Drill w Bill Hillmann

There is a lot going on here: combining a bumper thrown - interrupted by picking up a bumper in the 7 bumper lining drill, before picking up the bumper (interrupted mark); as well as interruption w obedience, followed by doing the Ydrill as a multiple retrieve. "Rainbow" does a beautiful job.
