There was an article in one of the rags up here recently saying because of the harsh winter the lil' blighters will be particularly bad this year.
Avon Skin So Soft moisteuriser. Midgey net for the head. Pitch tent in the most open space. Alcohol. A smokey fire. Copious amounts of marijuana jointage. More Alcohol. A mainly fried based, bad diet for a month before going "in-country".
And you may escape the worst of it and not end up looking like you have the measels/nits.
