You are really into flyfishing?
You wan´t to explore northern teritories?
So you have to get used to them….
Mosquitos, Midges, Blackflys, Horseflys….
Try to find support with a stuff called DEET (Diethyltoluamid). Northern mosquitos are having Autan and other kindergardenstuff for breakfast!
What else may we recommend?
Try to keep moving, even if you are eating. Blackflys will need a while to retrieve your smell.
Avoid doing things head first. They will take you as a reindeer.
