I'm the writing this on our 23 hour coach from Iguazu to Salta. (Please note, this blog was written two months ago on on 13th November!) This is only the north-east to the north-west of Argentina: it makes you realise how big the country is.

We just had to carry our rucksacks up a hill at 11am, and the temperature must be 38 centigrade and humid. As I'm carrying all of Jill's make-up my pack feels like there is a very fat child in it, holding some dumb-bells. Our hostel was at the bottom of a large hill and to walk to the bus station was like a biblical trial. I have never sweated so much. You could ring my T-shirt out, and then ring it out again. I didn't think there could be that much water in a person, I'm surprised I'm not a shrivelled husk now, like a raisin. I was the incredible leaking man and when we arrived at the bus station families of locals pointed in slack-jawed wonder and a pool formed at my feet. Jill had a slight glow to her.

It's air conditioned on coach now though, and apart from a dampness in the seat of my pants, I'm pretty comfy. Jill has her home-made Riveta sandwiches close at hand - the food they give you is not great, and also full of wheat.

Iguazu falls were astonishing. We went to the Argentinian side on the first day and then the Brazilian side on our second. The Argentinian side allows you closer to the falls and is possibly better, but you get an overview of the huge scale from the Brazilian side.

There are maybe ten huge waterfalls and lots of smaller ones stretching down both sides of a gorge where the River Iguazu takes a five hundred foot drop. The whole series is perhaps two kilometres. As you approach them through the tourist friendly walkways you can hear them long before you see them. The first sight we got of them made us gasp. The walkways take you right to the edge so the water drops away from under your feet. Everyone around you gets excitable and giggly, a bit giddy from it all. The Lonely Planet guide says that there's a theory that negative ions generated by the falls make people feel happy. But they're so dramatic and beautiful and huge that I'm not sure it needs another explanation.

Maybe my leaky body was somehow homage to the experience, but probably not as I'm just a very sweaty man.
