#1 RULE, always let someone know on a map where you will be and when you will return. Always makes me feel a whole lot better knowing my body will be found dead or alive if God forbid something happens. Permits are available and pretty easy to obtain. I have had good luck bush camping, the biggest problem I see being is people going to big with fires, a big no no as well as bringing unwanted attention to where you are. I only make fire in winter months out of necessity rather than want, keeping it very small.
