Threshold has one of the most intriguing outfalls off all the drains we've been to.
Micro, who I believe named it, sure came up with a great name that truely describes how the outfall feels.
When standing among the huge toppled over concrete churn blocks, the size and fortification of the drain becomes very apparent.
Even climbing through the outfall grate is more of a challenge than most.
The actual bowels of the drain are less spectacular, with some small slides, a small waterfall and the usual manhole junctions, but it doesn't detract for the excitement of seeing such a great outfall.
