In my defense, I was distracted by history. I grew up in a quiet suburban neighborhood in a smallish Indiana town. No sidewalks in that neighborhood, either. There was so little traffic we never seemed to miss them. (That's the house in the photograph. Nice neighborhood, except for the occasional ice storm.)
Growing up, my family vacationed on Florida's Gulf coast almost every year. It was, and still is, common among Midwesterners. I could walk for hours on the beach and be perfectly happy. Isn't the beach just a sidewalk for the ocean? So I grew up with a nostalgic affection for coastal Florida. Even when I lived in California, I imagined that one day I would live near the Gulf of Mexico.
Julie and I lived in North Carolina from 2001 to 2004. Of course, we lived in a neighborhood without sidewalks. Those were boom years for Florida real estate. We decided to buy into the St. Petersburg housing market even before moving here. (Don't laugh - you probably didn't see the housing market collapse coming, either. That's a topic for another day.) I came to St. Petersburg for a weekend in early 2004, spent a day on a whirlwind tour of houses, and took a bunch of photos to show Julie when I returned. It was snowing heavily in North Carolina the day we looked at photos of houses in sunny Florida.
Given this history, I think I deserve some slack for not thinking about sidewalks. Another factor in my favor, there is a county-wide recreational trail across the street. Plenty of walking/running/cycling to be done there.

Like the neighborhood where I grew up, our current neighborhood has little motor vehicle traffic. But the streets are narrower; the drivers here are faster and less civil. Certainly faster than traffic in ancient Kültepe. Julie and I both enjoy walking and we miss having sidewalks. We like living in St. Petersburg, it's just, well, we should have been looking for a neighborhood with sidewalks. Lesson learned.
