My SV Mk2 212 Bogner and Mk2 Shortboard has just completed two 5 hour outdoor, hot, dusty gigs in the California high desert at 105 & 109 degrees F in June 2013 (AV Swapmeet at 4 points, CA). I did not experience any equipment problems, so I'm glad my gear survived! It would be great to read about other players experiences with unusual weather conditions here.
