Can Someone explaing this riddle to me?! Travelling cities???

Question

Ok so its a game we used to play on the bus on baseball road trips. It goes something like: "ok your in Denver... you go 300 miles east and stop in Austin... you have 4 beers/ Stay 3 nights (or something odd)... you go north 6hrs and stop in ok city ( you stop for 4 days).... then they ask what city your in and some random dude says like "WASHINGTON DC!!!" and theyre right every d**n time... even when the joke teller tells me the city before hand.... the other dude always gets it.... I know they have codes for letters and beers and days/nights but i can't figger it out... someone enlighten me.

Answer 1

Ever notice that the answer was always either the city you were playing in or driving through? The question is" what city are YOU in? " The answer has to do with you,  not all the distracting questions about beers & days & nights.

Answer 2

I want to know too, I never herd this one before...

I need enlightenment too
