Sorry for the late notice on this (I just found out about it yesterday). All you packrafters out there might be interested in this event:
(quote from the Kennicott Guides site)The McCarthy Creek Packrafting race is a wilderness adventure race that combines hiking and packrafting. The event will include two courses. The 11-mile Z-Rock Down course, beginning and ending in McCarthy, and the 17-mile Up & Over course, beginning in Kennicott and ending in McCarthy.

Looks like a lot of fun!
