Bill Miller, passed away recently but left an incredible legacy. He was a driving force in the CBA and is responsible for the formation of the Orange County Blacksmith Guild (that I attend).

When the first blacksmith began hammering on a hot piece of iron little did he know how he was shaping the future.

It can truly be said that the first rocket to the moon was virtually launched from the face of the anvil.
