In his own words….(and a little bit of ours)

I was born on December 19, 1947 in a farmhouse 5 miles north and 4 ½ miles east of Covington, OK. Six weeks later there was a snowstorm that was one of the worst that the area had ever seen. The snow was fence-post deep, and roads were blocked for days.

My Grandma Reed seemed to think everyone needed a nickname. So she named me “Sonny,” and it pretty well stuck. My Granddad Reed’s name was Glenn so mom and dad planned on calling me Allan. Sonny was the only name my cousins, aunts, uncles, and other close friends of the family knew me by.

I lived in Douglas on the wrong side of the tracks from the time I was 5 until the summer of 1956 when I moved 2 miles east of Douglas and a ¼ mile north (on the east side of the road) on a farm owned by Bert Page. I lived there until I got married and moved to Edmond.

I went to school at Douglas for the First through Eighth grades and was the only boy in my class. I went to Covington for High School, graduating in May of 1966, and found the love of my life, classmate and 1966 graduating class Salutatorian, Susan Swaim.

After graduation, I went to Edmond to Central State College and Susan went to Tonkawa to Northern Oklahoma Junior College. We decided we were too much in love to be apart, and we got married on February 13, 1967 at my Grandparent’s home east of Enid. My uncle Ovid Granz officiated. I continued going to college for 2 more semesters. I needed to go to work to pay our bills, and I ended up getting a job as radio dispatcher for Edmond Police Department in April 1967. The man that hired me there liked me, and he also worked as a dispatcher for the Oklahoma Highway Patrol. He talked me into trying to go work for them. I went to work as a radio dispatcher (or “radio ditch patcher” as Amy used to say), for the Oklahoma Highway Patrol in Oklahoma City on February 1, 1968. Three of our kids, Arron, Brian, and Amy, were born in Edmond. I transferred to Enid in 1974, and we moved back to Covington. After the death of Susan’s sister, we purchased and moved into the Easterly house with Susan’s nephews, adding 3 teenagers to the mix. Our youngest son, Derrick was born in 1977.

In August of 1983 I was promoted to Chief Dispatcher at the Highway Patrol. I almost tried to make a career out of this job retiring May 31, 2000. From 2000 to 2020 I have tended both mine and Brian’s cattle and baled over 60,000 big round bales working with Brian. Susan and I attend football games, softball games, band concerts, and

I have 4 wonderful kids, 9 terrific grandkids. And I wouldn’t change anything.
