SPAR website states: "Since emergencies and natural disasters don't always happen in the summer, during Winter Field Day, frigid winds, icy limbs and bitter cold replace the thunderstorms and blistering heat of summer."
Winter field day is designed to test our abilities to respond to a disaster or emergency under winter conditions, and living in a part of Canada that has five good months of winter, it's probably a good thing we practice these skills. It's a hell of a lot different setting up at -20C than it is at +30C. In fact it takes about four times as long to set up in the cold as it does in the summer.
This years rules can be found HERE. Read them, they've changed this year.
I will not be able to take part until the late afternoon as I must attend the first planning meeting of the communications coordinators for the Rideau Lakes Cycle Tour. So, listen for VE3 Frozen Canadian Toes transmitting from Fort Henry Hill.
