Phil, it depends where you live as to whether sitting in the sun will give you a mega boost of D - in Boston, for six months of the year you will make no vitamin d, because no UV light of the right wavelength reaches the earths surface there or futhur north.
As for me, I live in the tropics (Darwin, Australia) and apparently you need to expose your face and hands for 5 minutes a day here to make 1000iu of D
If I lived in northern or southern latitudes, at the very least I'd be taking a multi with 400iu of D, and likely more
