From my travels in Australia, I’ve noticed that there’s an entire industry here that doesn’t exist in the USA – the backpacking industry.
Going around any big centers of activity – tourist hot spots, city centers, nightlife areas – and you see all sorts of businesses absent in America – hostels, backpacker flights centers, backpacker ‘hubs’ offering free (really crappy) wifi while selling you on travel experience packages (and invariably full of people checking facebook).
