Here is the latest email from Bill, received this morning:

We are in Wamena hoping to fly tommorow to basecamp. We have been
delayed one frustrating week, but everything seems to be in place to go smoothly from here on out.

Yesterday we went to a Dani village outside of Wamena and witnessed a
"mock battle". It was very impressive, and even the most jaded world
travellers really enjoyed it as an authentic experience. Everyone will have great photos and videos of that adventure.

We will fly on the Russian Kamov helicopter early in the morning tomorow, and hope to summit within a couple of days. Wish us luck with the weather, and we all hope to be home soon.
