Just got back from the Yukon with nary a mosquito bite. Used Downy
Fabric Softener Sheets. Rub 'em on your body, hat, shirt collar and
mosquitos will never land on you. Upside was that my bother and I camped
together for two weeks and arrived home smelling a little less like
two guys fishing in the Yukon for two weeks and a little more like the
wife's linen closet.

Cheers
