I know this is from 2008 but I came across it again recently and thought some of you guys might never have seen it.
To sum it up shortly: this guy basically crossed the US to pick up games at several collectors just to bring them to the CAX exhibition (
http://www.caextreme.org) and back of course !
Insane. Totally insane. But also the ultimate Arcade Lifestyle IMHO !
I copied some figures:
3052 miles round trip.
63 hours 34 minutes of driving time total.
12.3mpg overall gas mileage.
248 gallons of gasoline consumed
$1115 in gas money total.
About 14 major stops overall.
19 games total hauled by the FT Dodge on this trip.
