One of the reasons for my original post, other than the movie, is that a group of us go on a fly-in fishing trip to Northwestern Ontario every spring (about 100 miles north of Red Lake). In May and June, the Mosquitoes get so thick that they the form an opaque cloud. A mosquito head net is an absolute necessity at dusk. 100% Deet on all exposed skin, perm sprayed on clothes (they will bite right through anything but the thickest clothing), and a head net. Unless you're willing to spread DEET in your hair and on your scalp, a head net is a must.
