and gas wells.
At home, he was known for his storytelling skills, and enjoyed golf, fishing, hunting, and playing his
guitar (his prized white Fender Stratocaster). But his greatest treasure was his wife who was constantly
by his side to the very end, and his 3 sons who were also with him when he was ill. He lived to see them
grow into successful and caring young men. He also loved being a PaPa to his precious grandchildren.
