I love waterfalls, but at this time of year in Tucson there aren't any. I did see a great water track down the side of a mountain that will be a spectacular waterfall when it rains, but it's not quite the same. However, I also like mountains and rocks, so I drove my rental car up Mt Lemon yesterday, and took lots of photos. (I am getting good at driving on the wrong side of the road but I do keep trying to get in the passenger side of the car every now and then.)
Up on the mountain it is about 10 degrees C cooler than down in the desert, and it's fascinating to see the changes in vegetation as you go up. First there's saguaro cactus and desert plants, then there's scrubby trees (many were dead, because there is a drought here and people have told me the cacti are suffering too), then there are wonderful spruce forests.
In Australia, you can smell eucalypts in the bush; here it's the the smell of spruce, and it is different from Australian pines. I contemplating walking - hiking, everyone calls it here - but the bookshops were calling me and it was a bit hot. Maybe next time.
I managed to fit in three bookshops yesterday afternoon, but how I will carry my bags today is another question. I have discovered that my suitcase is basically stuffed (as in broken from being bashed around by the airline luggage department) but I think it will make it home OK. As long as no one drops it from forty feet up.
I feel like I only just got here and now it's time to leave. But I'm already lining up which books I'll read on the plane. So much to choose from...
