yes alaska was a computer simulation I know but mexico is in maybe from vegas at least a week or two away walking and did you hear of a train tracks would be their and as a fuel you could brun wood that woidn`t take long at all. by the way do you remember how you get to the pitt if their tracks then their has to be some at vegas and I will not lie the UK would be pretty cool.
Failure...You are failure.
Firstly, if you knew it was a computer simulation then you wouldn't of said that. Maybe? Obviously you have no clue how far apart Mexico and Vegas are. If you were to go to Tucson (right near Mexican border) from Las Vegas it would take about 7 hours. And that's using a car and going by roads/freeways without radiation and all kinds of hostile enemies out and about wanting to kill you along with set of mines and all that stuff. las Vegas to Tucson is 409.89 miles, walking briskly (because if you run, you'll only die tired) that would take 5.7 days, about 6. But then each of those days you'll have to sleep so now it'll take 7 days. Now we have to include the equipment we're caring (weapons, aid, etc.) so now it's probably going to take 14 - 21 days. Then you have roaming threats all around you (mines, mutated creatures, people that want to kill you, radiation, etc.) so basically it's going to be a lot longer based on how good your combat skills are (but this is realistic so taking out hundreds, even thousands, would be very unrealistic and if you even did do it I am going to guess it would take years) then you have to add stuff like radiation and mines, mines can probably be avoided and disarmed but if your explosives skills aren't very good you might get killed. Radiation without treatment would be deadly. Then you have no roads or freeways or anything any more so add about another year. So basically,
it would probably take more than a decade to get to Mexico if you survive the whole trip in one piece.The train tracks are only around in Vegas and that area so fail. And Pittsburgh and D.C. are not only in the same country but are right near each other. You failed...again. Oh and Europe is not UK, failure...
