You have to be a SERIOUS fisherman/camper to venture into an area that's so bug-infested that you need that level of deflection.
The mosquitos must be the size of Messerschmidts.
I'd rather camp in Moab where it's hot and dry and I just have to check my boots for scorpions in the morning. (call me crazy) Then again the fish aren't biting in the Moab area.
I think that a genuine bug/rock/object deflector that would save the windshield would be a big seller. If you could make it look cool it would sell even better.
