The littlest red, white and true-blue Yankee Doodle Dandy in this year's Modesto Independence Day Parade could not get any younger and still be eligible to ride. Vanessa Avalos was born on July 4, 2008, and will turn 1 on the day she joins several others sharing the nation's birthday on a decorated flatbed truck. Another will be John Hernandez, who will turn 53 and who is the boss of Vanessa's father, Danny Avalos, at Memorial Medical Center. Anyone with the right birthday credentials can ride on the float by calling its originator, Doris Scalon, who will turn 79, at 524-3246. She's been spearheading the float for 19 years.
