How the eff and jeff does anyone live with those in their house in Aus? You must all be a tough bunch I dare say!!! That stuff should be in the creepy crawly section of a zoo, ok they eat cockroaches and what not, still would want to see one "chilling" on the ceiling inside.....
Fascinating stuff. Draining has always been a niche interest to us but being underground these days is a nice antithesis to the rooftopping culture that's been booming here (much to our chagrin)
Hope you had a good time in our city. Do get in touch next time (or anybody) if you ever stop by HK.
