Something to ponder, just in case anyone was reading this thread.
On the third day of the race, between the 90 and 130 mile checkpoint, my mate Yaki fell into the Skwentna River up to his chest. Somehow he got out* , managed to take all his clothes off and to get into his sleeping bag and bivvy. If I am correct, the river has to be crossed several times in that area and theoretically the ice should be thick enough for that.
(*Yaki had already practiced, unintentionally, this particular routine about 30 years ago in Scandinavia doing a solo winter crossing lasting a few weeks)
The next day we started to wonder what had happened to him, but because the weather was particularly bad, it was assumed that he was either heading to or staying inside one of the nearby (well not so nearby) cabins. For a couple of days the satellite phone communications were down in the area. Another two days passed , so the rescue squad was mobilised and he was found this morning apparently in relatively good form.
So, another amazing adventure that I will be glad to hear first hand...
