456 PI MU EPSILON JOURNAL f.'o'l>IANA JONES AND THE QUEST FOR ANTICONNECTED DIGRAPHS<br />
----------------------------~~~~~~~<br />

"I have the utmost confidence in you son. "<br />
"So you'd like to go first" Indiana jokingly asked.<br />
"Harumph. " Henry made a half-laugh, half-cough sound and replied,<br />
"Ach, Junior, you've come so far, but still some things ... "<br />
"Never change. I know Dad. And you either. Let's go. "<br />
Following their prescribed route, with grumbling and bickering along<br />
the way, after what seemed an eternity, they found themselves once again<br />
under the African blue sky. Henry Jones piped up, "Ah, I can't wait to get<br />
back home and we continue to study and formalize our results on graphs.<br />
You know, it would be nice to write up the results we found into a paper and<br />
submit it for publication to the <strong>Pi</strong> <strong>Mu</strong> <strong>Epsilon</strong> Journal so that many math<br />
students can see what we've done and perhaps even find more theorems. "<br />

"Umnvn. .. " Indy had the sheepish look again. "You were serious about<br />
that Dad Oh, forget that, of course you were. You realize that was the<br />
kind of promise a son makes to his father when he realizes there's a good<br />
chance they may not make it out of the situation they are in, don 't you I<br />
mean you aren't really going to hold me to that" Indy prodded his horse<br />
into motion.<br />
"Junior!" Henry shouted, but his son was already on the go and he had<br />
naught to do but to follow. He would make Indy see the virtues of his<br />
methods yet. But probably not this day. The pair charged off across the<br />
landscape and finally disappeared as fading specks melting into the African<br />
setting sun.<br />
