I didnt say they werent dodgy I hate demountables as a rule This doesnt alter the fact that they remain as an important part of CHS history   As for your objection to the word permanent you might also be aware that until recently the entire school was scheduled to be levelled to make way for unit blocks with all the students to be relocated to the Kuringai College siteThis was  only avoided by the rerouting of the EppingChatswood railway  Nothing is permanent by those standards As For Freds contribution I can only urge him to pay attention I havent proposed making any comparative entry merely that the ESL buildings were used exclusively by Vietnamese refugees
