What is the main conflict in Woods Runner by Gary Paulsen?

"Woods Runner" is the story of Samuel Smith, a thirteen-year-old boy living on the western frontier of Pennsylvania in 1776. Samuel lives with his parents, Olin and Abigail, in a settlement of small cabins surrounded by thick woods. Samuel's parents are newcomers to the frontier, having been raised and educated in eastern cities. Samuel, however, has grown up on the frontier and is most at home walking and hunting in the deep forest. His skills have far outpaced those of his parents and he has become the provider for his family.
