I trode across a suspension footbridge (The Swinging Bridge over the
Illinois River in Kerby, OR) yesterday and admired the engineering.
12x12" uprights about 20' tall and 1" galv steel wire ropes supporting
about an 80' span. I wonder how far they had to sink the terminations
to support that structure...

Oh, sink the terminations? You mean, like, in concrete? Oh. We were supposed
to do that?...
