Spoon and fork
By the way, did you know that unlike in East Asia, chopsticks are generally not used in Thailand, or in the rest of South-East Asia? Until I arrived here, I wasn't aware of this; but after having now spent a month in Thailand, and having barely used a pair of chopsticks, I'm pretty clear about it. Apparently, chopsticks are the traditional eating utensil only in China, Japan, Korea, Taiwan and Vietnam. In Cambodia, Laos, Thailand, Burma, Tibet and Nepal, chopsticks are used in a limited context, and even that is merely as a result of Chinese influence. In Thailand, a spoon and fork is the preferred utensil set when eating all kinds of foods; except in the case of noodles, when chopsticks may be used. So if you're chopstick-challenged (which, incidentally, I'm not), then don't worry: it's not a required skill when visiting Thailand.
When I got in to Puerto Iguazú today, my first order of business was getting myself a Brazilian visa. Everyone from Australia, USA, Canada, and a few other countries needs a visa in order to enter Brazil, even as a tourist (unlike with most countries in South America). I'd head that it's much easier to apply for a visa here in Puerto Iguazú, than it is in Buenos Aires. Well, I can certainly believe that, because it couldn't be much easier up here: the consulate gave me a visa virtually on-the-spot, within just one hour! Plus, they didn't bother to check all those annoying things such as an onward ticket, an address of residence in Brazil, evidence of sufficient funds, etc. So good on ya, guys: in Puerto Iguazú, they make your life easier.
Sacsayhuaman and Qenko
I didn't make it to Sacsayhuaman (a.k.a. "sexy woman") or to Qenko last weekend, when I got lost in the mountains; but I finally reached them this afternoon. Myself, Monika, and Juan Carlos wandered up from central Cusco to these nearby Incan ruins after lunch today, and we explored them at our leisure. As with Tambo Machay (the only ruin I did reach last weekend), they're nothing compared to Machu Picchu; but they're a convenient day trip, and they're beautiful and interesting nonetheless.
