You should organise an LFS crawl. Then your mum won't have to drive you. Of course you'll have to make sure someone coming on the crawl can drive. When I lived in Sydney 14 years ago (yikes!) I drove around to all my favourite aquariums nearly every Saturday!! Auburn, St George, Lam's (not the one in Paramatta, there used to be one in Campsie or thereabouts) and Manly were my regular stops. I kinda miss those days (except for the living away from partner and family, and never having enough money part).
