Oh boy... that snow! The barn was completed in Nov 2008 right before the worst snow in 30 years (doesn't look so bad in that pic - it got worse and lasted for over a month). Seriously, moved the horses in from field shelters they were living in to the barn and it started snowing that night.
The barn is pine and cedar and has not been treated. Still looks great and has weathered nicely.
