Murphies law of construction states that when ever a building is vunerable you WILL have severe wheather. I had a large tf stripped and ready for disassembly, ie pegs loosened or cut ,roof removed etc. and a micro burst blew threw that night. We had a sale booth set up by the road and we had stuff scattered for miles. The frame had no damage. There is no such thing as over building or over bracing. another time I had a camp jacked for a foundtion and Montague NY got the national record for snowfall . When we shoveled the roof we were throwing snow up over a bank to clear the roof. That record held till a couple weeks ago when oswego NY took it. Expect the unexpected!
