I have been at it since 89, and I have been thinking about this cold weather.
Other than not being willing or able to drive in the snow and ice, the only reason that this winter feels harsh is the fact that the wfp gear has frozen in the van.
Ok it has been a tough and cold winter, but I remember 1997 having steady minus temps with troughs of down to -15. I was able to work happily (trad) in those temps, as long as my water was warm and not frozen in the bucket. This year we have a lot more people relying on wfp, who are scratching their heads and wondering how to make a living when all their gear is frozen solid in the back of the van.
The answer is to be prepared to put in a hard days graft when the going gets tough, grit your teeth until spring and your customers will respect you for it.
