My thoughts and prayers are with your loving family. Flashes Rule!
In 1970 My Mother and I visited Greg in Germany. He requested that I bring him a Led Zepplin tape and we zipped all over Europe in his white VW that he called the "Silver Bullet" listening to Led Zepplin for nearly a month. I was his copilot my mother was the backseat driver. A trip of a life time and I shared it with my brother.
Rocks are a symbol of strength, be strong in this time of passing
