I can go a few days, depends on what I'm doing, last time I went camping I really didn't want to go, but I ended up getting roped into being the "adult" for my sisters camping trip, I lasted about 6 hours before I drove into the nearest town and dropped the cash for a mobile internet plan.
But the time before that I went hunting with some mates, we were out for a week, didn't bother me at all.
