Another difference; I'd never carry a cell phone wall charger in the woods, always in urban areas.
I used to think the same thing, until I started noticing the outlets at out Provincial Parks and Conservation Areas. In this day and age, so many people camp in trailers and RVs, not to mention carrying cel phones, gps, etc., that most parks seems set up for them. Of course, I'm a Luddite when it comes to being in the wilderness, so don't usually carry stuff that needs recharging, but my husband and kids make-up for my shortcomings.
