Dale Earnhardt just received a generous donation for this great cause

Dale Earnhardt Jr.'s farewell tour just reached peak awesomeness after Charlotte Motor Speedway donated $100,000 to underwrite and establish the Dale Earnhardt Jr. Concussion Research Fund at the Carolinas Healthcare System's Levine Children's Hospital.

Earnhardt has been steadfast in his request that any donations, gifts or recognition on his behalf have an effect on society.

The donation isn't lost on Earnhardt's documented history of concussions, having missed racing time during two different seasons after experiencing concussion-like symptoms.

In 2012 he was sidelined for two events, and last year missed the final 18 races after his symptoms from a wreck at Michigan got progressively worse.

"We have a lot of history with concussions and awareness and rehab and all that good stuff, so this is something that is actually very close to my heart," Earnhardt said during the presentation of the donation as reported by NASCAR.com. "I hope to be able to continue to help others going forward. This is a great way to do that, so thanks again."
