Nothing submarine-related here, just "proud Dad" pictures of his youngest kid on his mission in northern Chile. He's on the left in these two pictures:
And on the right on these two (his "Mission Mom", the Mission President's wife, is on the left):
He's currently in Calama, Chile, which apparently gets below freezing now while it's winter down there. We sent him with a nice long coat, but based on these pictures he's only wearing the liner that came with it.
