PHILADELPHIA (AP) — A 4-year-old girl has grabbed her purple raincoat, slipped out of her house at 3 a.m. and hopped a Philadelphia bus in search of a snack. Bus driver Harlan Jenifer says the girl swung her legs in a seat as she chanted, "All I want is a slushie." Authorities say the girl's family didn't know she had awoken and unlocked the backdoor to start her trek during a downpour early Friday.
