On January 17th I joined up with the non-motorized snow day at Green
Rock.  Along with about 80 people we ventured up WYO 130 to around the
science camp/ess-turns where it was determined that the point was made
about public use and the fumes were too great to continue on the road. 
I stuck with the main party as we made our way toward the top of the
Sally Creek drainage then returned to Green Rock.  There were no
injuries and with the presence of rangers, no conflicts arose.
