As we IndyCar fans look back on 2015, there really is a lot to be thankful for. Of course, there was also tragedy as we lost Justin Wilson to a fluke accident at Pocono in August. But we can be thankful that the IndyCar community stepped up and raised over $600,000 for the care of his young children. The efforts by Graham Rahal and several others shows the strong bond among those who are competitors on the track, but close friends off of it.
