Perhaps it's this news article that gets me a little worried about tree branches:

An adult sycamore tree, weighing several thousand pounds, fell on top of the family's tent about 6 o'clock this morning, Tang-Smith said. State park police arrived about 6:15 a.m. and found the man and his wife inside.
Tang-Smith said the Somerset County family had been camping with their children, a 10-year-old boy and 12-year-old girl, as well as a 9-year-old cousin. Authorities said the children were unharmed. It was not clear where they were when the tree fell.

Happened just a few miles from me...I know guys who were on the call. It wasn't even bad weather...it just fell.
