Dale Earnhardt Jr.'s crashed car collection includes an IndyCar of Will Power's hanging from a tree

during NASCAR Sprint Cup Series Gen-6 Testing at Texas Motor Speedway on April 11, 2013 in Fort Worth, Texas.

Dale Earnhardt Jr.'s car graveyard on his property in North Carolina isn't limited to stock cars.

The newly-Twitterized Junior said as much Thursday, responding to a fan who asked if a car of Will Power's was included in the collection of wrecked race cars. Power drives in the IndyCar Series.

And then came photo proof:

Power suffered a broken back in the crash at Las Vegas Motor Speedway in 2011. The fiery 15-car pileup in the final IndyCar race of the season claimed the life of Dan Wheldon, who had won the Indianapolis 500 earlier that year.

How did Junior get the car? Well, it's not hard to guess.

Brad Keselowski, the 2012 Sprint Cup Series champion, drives for Team Penske, the same team that Power drives for. Before he moved to Penske in the Cup Series, he drove for Junior's Nationwide Series team.

The car that Juan Pablo Montoya crashed into a jet dryer in during the 2012 Daytona 500 also rests in the car graveyard.
