Before we hit the road this season, we were listening to the Puzzler on Car Talk and I was proud to answer it quickly for once.

It had to do with palindromic numbers, which I wrote about when our odometer reached 77,777. That was a while ago, we recently reached another mileage milestone when we joined the 100,000 mile club in our trusty ol’ Dodge.

But back to that Puzzler, I’ll try to summarize how it went…

A guy gets in his car one morning and notices his odometer reading is a palindromic number.  When he arrives at work just across town a few minutes later, the odometer is showing another palindromic number. How far did he drive?

As a refresher, this any number that reads the same forward and back, like this…

Palindromic Mileage Puzzler Answer

Watching a digital odometer isn’t nearly as fun as watching 100,000 miles roll over the old way, but we were in a rather unremarkable area of Arkansas when it happened anyway.

How many miles have you put on your rig and where were you when you hit a memorable milestone?

Earlier in that day of the Texas flash flood that nearly swept our trailer away a few months ago, we watched the odometer in our truck turn 77,777 miles. While that evening was full of excitement, normally such an event would be a big deal.

Well, at least for me.

Putting 77,777 Miles On Our Dodge Ram 2500

On long stretches of highway, what I used to consider numerical anagrams are always something I look forward to. Then I learned at Google University that the proper term for such a sequence of digits is a palindromic number. These are numbers that read the same forward and back. And when the mileage gets up there like it has on our Dodge, it’s fun to figure out the next palindrome we’ll reach in our travels.

OK. It’s  no exciting, rip roaring, click you heels kinda fun. But it does give a long haul driver something to think about for a few miles. Like what would be the next palindromic number in sequence in our example here? Hint, we passed that over a thousand miles ago.

The first few are easy. Not including single digit numbers, they begin with 11, 22, 33, 44… etc. The fun, however, doesn’t really begin until you get to much larger numbers, like 101,101 for instance. Maybe we’ll hit that one during our next season on the road down south.
