LAKE CHARLES, LAUnbeknownst to him, 27-year-old Ron DuPree attended the last great party of his life Saturday, as a 3 a.m. coupling with girlfriend Tamara Harris will result in a child nine months from now. "That was the best party ever," DuPree said to friends on Monday, oblivious to the seed of life now growing in his soon-to-be-wife's womb. "I was so wasted! God, Tamara and I have to start getting out on the weekends again." In addition to enjoying his last great party, DuPree will also soon bid farewell to liquor, cigarettes, and most of his current friendships.
