I can't figure out how to change my location from Manhattan (I'm in Australia)
1. Did you enable the 'Share Location' option in your browser? It should have appeared on pageload.
2. The 'More Options' should allow you to change the city/area.
Also, could you let me know which browser and OS you're using?
EDIT: corrected typo.
(EDIT: I reloaded again, and I saw a bar come down asking if I can give this site my location. The bar was in light blue, and it was well camouflaged with the title of your page, and it also disappeared in a few seconds, so I never saw it the first time)
