No humidity... hmm... In Buenos Aires you can sweat by just breathing... let's say that some unique days all your stuff is wet, and you can "feel the water" in the air, literaly. If you left a paper on the table, or you are carrying it in your hand and walking, you'll notice is all wet in about... 10 minutes .-.
Where do you say you live? Phoenix? I need a try of that heat, sounds too different xD
