Probably much more than safety from potential "bad guys," I'd worry about water and bodily functions when camping in random places. How much water will you be able to carry with you? How far between places you can refill? How much do you think you'll need for dishwashing, and how long can you go between sponge baths? (Two days is about my limit before my skin starts walking away without me, but I'm soft. ) Is the soil and privacy situation always going to be conducive to digging latrine holes? Cornfields are great for #1, but you don't want to disturb the roots of someone's crops, and I have no idea how often you'll be going through woods that are deep enough for privacy but sparse enough that roots won't prevent your digging.
