Weather - hey guess what sunny and cold... (which incidentally has started making my nose and lips fall apart)
Location - errmm in Tibet...
Into seriously naff roads - 4x4 is a really good idea (and most people use these if going to Nepal) quite a few people trying to cycle up to everest basecamp (not so sure is that great an idea, if only as you get covered in some much dust from the roads...) More isolated spots
Unusual sights - tibetan wearing oakleys..(fake)
