Using that oak chart, this tree with a girth of 19 feet (in the 80's, most recent measurement I can find. I want to measure it myself!) should be at least 400 years old. It is in Fowler park, Geneva AL.
Have to get pretty far back to get the whole tree in a pic.
There are bigger trees pictured and discussed here:

I'm not sure oaks from North America can be quantified with the same formula as oaks in England. According to that chart, the trees at Oak Alley Plantation (in above link,) would be around 1,000 years old but it's considered a fact they were planted in the early 1700's, so are around 300 years old. That's a pretty big difference.
Guess that's also why pecans aren't on there (the info is from England.)
