Read the following context and answer the question.
Context: No , real bear drama . Woof , Grr , Woof , Grr and all that , but let me tell you , one of our volunteers was charged by a mother bear that was roaming our camp . They did n't realize it was a mother bear until it charged poor Donna ( who was fine and untouched ) and then decided to hang out in the shrubs behind MY tent . Apparently , the mother bear sent her cub up into the tree just outside my tent , and would n't leave or immediately communicate with her cub .
Question: Why was it roaming our camp ?
Answer:


The mother bear left her cub nearby .
