   Predicted Attribute: Presence of a baseball game at Dodgers stadium

	81, but 2 home games occur during periods when the sensor was down
	Note: this is an incomplete set, other unscheduled events likely occured

8. Missing Attribute Values: 2903 (represented by -1)

9. Other notes:  This loop sensor data was collected for the Glendale on ramp for the 
	101 North freeway in Los Angeles.  It is close enough to the stadium to see 
	unusual traffic after a Dodgers game, but not so close and heavily used by
	game traffic so that the signal for the extra traffic is overly obvious.
	NOTE: This is an on ramp near the stadium so event traffic BEGINS at or near
	the END of the event time.
