The intersection of West Gateway Boulevard and North Congress Avenue in Boynton Beach, Fla. (pop. 60,000), is nine lanes wide, busy even at 11 p.m. on Sunday night, as it was at that time in July when a 2-year-old girl darted across, a combination of good fortune and sometimes-rare Florida driver alertness allowing her safe arrival on the other side without a scratch. "It's a miracle," said Harry Scott, who witnessed it. "I'm telling you the truth." Mom Kayla Campbell, 26, was charged with felony neglect, as she appeared "oblivious," said police, to the child's absence from home.
