Exploring Storm Drains in Adelaide

One of my many and various hobbies is exploring storm drains underneath Adelaide (ideally when they're not full of water). But I don't do this on my own - I participate in "Expos" (ie exploration expeditions) with the Cave Clan, a club of urban explorers that have groups in many Australian cities, and who have been exploring drains (and other hard-to-get-at places) since 1986. I started doing this during 2003, and have photographed and written up most of the expos I've been on so far. I present these writeups here for your interest and entertainment.
