Back in 1966 when I was attending college in the small Missouri town of Canton on the banks of the Mississippi River there was a 19 year old blond kid from Chicago, Gerry Glombecki, who lived in my dorm and had what was probably the first skateboard the town had ever seen.
Gerry was a carefree sort who always sported a great smile. I knew him for a year before I left Canton and, of course lost contact with him. Withing the last year, through Facebook, we reestablished contact of sorts. Gerry had gone on from that small river town to become an accomplished musician and a fixture in the Tuscon, Arizona, music community. He was inducted into the Arizona Blues Hall of Fame and was a founder of the Tucson Folk Festival.
This video shows Gerry playing slide guitar, and one of his sidelines was the making and distribution of authentic guitar slides: http://gerryglombecki.com/Sliders.html
