To be honest with you I try at all times to sleep in a nice bed in a hotel.. Now if were in the forest, I wouldn't have a problem at all as long as you keep a nice fire going that should keep wildlife out of the area... And make sure no food or traces of food is left out.
Put the fire completely out when leaving.. not only will it keep you from starting a forest fire, I will keep you from getting a nice fine if you get caught!
