The thread on Best Fly Fishing Vehicles got me thinking that I too ought to take advantage of my vehicle (Explorer) for simple sleeping quarters once in a while, but also brought me to a rookie question on the matter: I'm assuming you guys crack the windows and/or sunroofs in those situations for ventilation. What do you do about mosquitos during the warmer months? I'm one of those guys that seem to be a magnet for those God-forsaken insects, and I know it would be the case with windows open even a little bit on a balmy night. Can't say I relish the idea of slathering up with bug dope right before turning in, but obviously a vehicle like mine doesn't have screens to keep them out. Has anybody figured out a way to stay cool without the windows cracked and/or to keep the bugs out when they are? Thanks in advance.
