Late Spring or Early Summer in NC should avoid Hurricane Season,
but it might be damp enough for mosquitoes and maybe the ticks
will keep you company. Make provision for them: netting, chemicals,
etc.
Most places will only let you stay 2 weeks, and most likely you will
be detected. Your car, your fire, your tramped trails, help them find you.
What color will your tent be? Remember, you are not a through-hiker,
you are a squatter.
Scrounge some free pots, a few of them need to be big. The big ones
can be dedicated to heating water (purification) and soapy water washing
you, your clothes, your utensils and dishes.
Stay reasonably clean, and get real clean before going into town.
Have town clothes ready and clean, always.
Some people will treat you real bad, if you stink.
Small, all digital, transistor radio. Extra batteries.
A clear tarp is wonderful on rainy days. Sit under it and read, or just
look up at the sky and trees. A real morale builder.
No camp is perfect, but you need to plan the best you can.
Pay attention to logistics of your camp(s). Have an alternate planned
in case they make you move. Think about the water haul, the food haul,
etc. Is there an easy path to get out, if injured; is it downhill?
Will your car be vulnerable to break-in, or car-theft, or towing, if it is
left in one pace too long?
