Machu Picchu yesterday and today. Tour yesterday in rain. Everything vertical, much with steps higher than my knees consider comfortable. Despite that, it's totally AWESOME. A larger area than it looks in typical photos. Definitely a You Have To Be Here experience that photos do not do justice to.
Staying at Sanctuary Lodge, just outside entrance to Machu Picchu. Another very nice, very expensive hotel, with great food. Have discovered the Pisco Sour. YUM!
EDIT: Photo album from this part of Peru is here.
