Who says you have to setup camp early. I generally search out the campsite and find a campsite during daylight but I never set up camp before 11PM. Generally by then the mosquitoes have went to bed for the night, not always and I don't have them to deal with when I set up camp/sleep. Search out the campsite and then head into town, Grab supper, ride under moonlight, whatever. Just hang out away from the campsite until your normal bedtime and then off to the campsite and setup camp and head straight to bed. That will help you kill plenty of time, keep you away from the bugs and boredom.
