It Seems Only Fitting For The Most Popular Driver In Nascar, Dale Earnhardt Jr. To Announce His Retirement The Day After A Race At The Track Where His Father Won His First Race. Dale Jr. Missed Half Of Last Season Due To A Concussion, But Returned To The Track This Season. He Said Yesterday, He Wanted The Opportunity To Go Out On His Terms. Dale Jr. Will Still Be Part Of Racing Even Though Not Behind The Wheel.
