I have to agree about whitesocks and no-see-ums (even if I have never owned a head net). I have been to Japan, India, Mexico and Hawaii. The most plentiful insect encountered in India was Schwartzenroaches, no trouble in Japan or Mexico. Near hot pools in Hawaii I did encounter some Alaska like no-see-ums but as soon as I was away from the brush and the hot pools they disappeared. There are no insects that stop tourists from enjoying Alaska. They are no comparison to blue glaciers shedding huge chunks of ice and creating massive waves in the copper river. Snowcapped mountains, rivers, lakes and wildlife abide. The people there are the best. Dont let the bugs stop you! Its a place you will always remember!
