Old Oak

We've always wondered how old the big White Oak tree behind our house could be. Today I measured the circumference and, based on this chart, the oak is about 275 years old! That means that it was probably started from an acorn dropped or buried by a squirrel in the 1730s. Here's a picture of it (to give you an idea of its size, the swing attached to it is a 2-person swing -- about 3 feet wide).
