Should have been . . .

. . . used in the first place – concrete posts.

We're having to replace a long fence up one side of our property.  Many of the wooden posts are rotten, but I would have merely reinforced them with the excellent fence spikes from RSL Engineering but an animal undermined one end by attempting to dig a burrow or set so the whole fence has started to sag somewhat.

We hadn't budgeted for it, but needs must.
