The extended road trip finally arrived at its western terminus in the Texas Hill Country. This also marked my first visit to Burnet County, a rural locale situated northwest of Austin. Locals pronounce it something like BURN-it, and that’s how it felt as the mercury hit 103°...

Program Note: This month is Philadelphia month! Don't get too excited.  In the past I've done San Francisco Week and New Jersey Week. Much of that content was posted to Twitter. These things happen when I suddenly find a trove of information about a specific place. In this case...

The heat really cranked up as we entered Texas, never dropping below a daily high of 100° Fahrenheit (38° Celsius). Here my hybrid working vacation transitioned completely to pure work for a day. That’s where I needed to attend meetings at NASA’s Johnson Space Center in Houston...

Next we returned to familiar territory. I’ve mentioned the Mississippi Gulf Coast many times on Twelve Mile Circle because I go there fairly regularly and I have a lot of family there. However, my last trip was way back in 2019 and only for a long weekend. Somehow I never figured...

I have a deep admiration for the stirrings inside animals that drive them to undertake thousands-of-miles journeys to far flung locations, and back, in concert with the passage of the our earth around its sun. I’ve reflected on it in writing what became a surprisingly...

Sure, the southern United States has more than its fair share of pesky bugs that most people actively avoid. Mosquitos, horseflies, and palmetto bugs probably top that list. So it probably sounds strange that we devoted an entire day to insects, particularly to the appreciation...
