"With that [the tracker], what I normally do is it goes into my back pocket, so if any of you guys ever come out, you'll always see maybe a little bulge..."
From the blog:
The tracker, in response to a couple of queries on social media, had remained in the RV during our separation, which it does much of the time. Itâ€™s purpose is for folk to see where we are at, at any given time, not to measure speed, mileage or performance â€“ thatâ€™s what the GPS watch is for.
So is the tracker with Rob or in the RV? Let me take a wild guess: it's on the RV when something fishy or unbelievable happens with the speed, a shortcut, or otherwise unaccounted mileage; it's with Rob when everything appears normal.
