Practicing Out to A Tunnel

I set up our course at home with a tunnel under the dogwalk and one under the A Frame to practice Out to a tunnel. Wyatt and I are doing better at pushing out to the tunnel with my improving and more consistent handling of this situation. I am pushing out against his line about 1/2 way between the previous obstacle and the tunnel, saying Out Tunnel, and also pushing with my hand towards that same 1/2 point. Now I need to gradually work from farther away.
