We also did a little shooting on the targets, but had to reset them by hand after knocking down all we could see from one spot, since the lines were frozen into the ground and covered with over a foot of snow in some areas.
This is what it looked like out there.
A target at 30 yards was blocked by a chunk of snow, so I estimated where the hit-zone was and attempted to shoot through it. I watched the hole appear in the snow and the target fall. I took a pic on an angle where you can see the hole and the hit-zone.

A fun day all in all. Thanks for the help and company, Dave.
