GREENVILLE, Texas — It’s official. My mind is totally blown apart.

I ventured to Greenville today for a story I am going to write for KETR-FM’s website, KETR.org. I won’t divulge what’s going into the story. I merely want to take a moment to tell you that I have been bowled over by high-tech genius.

My visit was with the Greenville Electric Utility System brass. I met with GEUS’s general manager, Alicia Price; with marketing manager Jimmy Dickey; with Internet manager Jason Minter and with Terry Walthall, whose business card describes him as a “Headend Specialist,” which a kind of code for system operations manager … the guy who knows which buttons to push and which wires to connect.

Our visit was informative in the extreme and I look forward to posting my story about Greenville’s cable TV-Internet system on KETR.org next month.

However, my mind was blown as I tried to process all the technological expertise that was being demonstrated.

My session with Price, Dickey and Minter ended with me recalling how it was when I was a youngster, how we were able to watch three whole TV channels. How we had to get up off the floor or out of a chair, walk to the TV set and turn the knob on the front of the set to change the channel. I asked Minter if he remembers TVs that took about a minute to “warm up” as the tubes inside got hot. He quipped about how the “vertical hold” would scroll the image up and down.

I mentioned the rabbit-ear antenna on top of the TV set and how we occasionally had to wrap aluminum foil around the end of the antenna to get a stronger picture.

Then I mentioned how Dad sold TVs and other appliances in the 1950s and how our family acquired one of the first televisions in Portland, Ore. And then I told them about the time color TV came into being and how my sister and I would host “TV watching parties” in our living room with neighbor kids who gathered with us to watch cartoons in color.

I am 70 years of age, but those memories remain fresh in my noggin. Today’s session with the high-tech powerhouses at GEUS only reaffirmed what I knew, which is that we’ve have circled the solar system hundreds of times in our quest — and our discovery — of technical know-how.

It has blown my mind.
