Roger Penske employs two of the best well rounded drivers and people in the sport. Every NASCAR driver is a philanthropist to some degree because of taxes. I feel these guys truly put heart behind the dollar and that is what means the most.
The truth in what you said is found in the real time that Logano spends with not only Gavin but others as well. It is one thing to give tons of money to the needy and unfortunate (it is great) but giving your time is much more of a selfless and noble action. So yes, Joey Logano is without a doubt, a noble and VERY good man. He is not the only driver from Nascar to be this genuine though.
