He isn't hurting. But yes it is still his image they use.
I'm sure he isn't and if he is still the same Burt, it would matter to him anyway. He was the quintessential 70's hippy, lived in a barn without a care in the world. Was the first vegetarian I ever met. As a boy, I had a hard time understanding why a guy that looked like he was starving wouldn't eat the "good stuff". But boy could he eat the other stuff my mom cooked ;)
One day he packed everything he owned into his van and headed for Maine....
I'm trying to convince my Dad to stop by Dallas' campground on his way to Deland this winter and chew the fat with Dallas. He has much better stories about Burt than me. After all, I was just a young un' and Burt was a scary looking dude at the time :-P
