6 of them added up to 15,000 miles (Each ranged between 1,300 to 3,000 miles. Googled them just now.)

Even since 2012, there have been 4, including 2 of the 3,000 mile ones (there and back again within 3 months, heinous mixed episode).

I'm a little older than you. Too old for this ****. I want to stay put. (I did stay put for around a decade once. Amazingly enough.)

Congratulations, apfei!

(P.s. Thanks for the mathmatical distraction.)
