In went to this cabin in 2012 and was happy to see a major over haul in process. New foundation, mini dock, and a new roof. Fishing is reported to be good and there is a trail to cabin which had some major work done on it in 2005.

This dock will work OK, bring 2 good bumpers and a little extra line.
