mmmh... I don't know... The wasts are very dangerous.
I know some notions to survive for a little, i think, but I've no direct experience with firearms... very bad.
The priority will be gather a group or join in a community. A lonely traveller has few chances to survive.
After that, my group will go to a place where learn combat skill and others useful knowledges.
NCR is a good choice, but Redding too (Redding is more dangerous and has lesser goods and peace, but it's good to learn the "Wasteland Way"). Good jobs are guard of caravans and, maybe, sheriff's helper...OMG!
The Morton Brothers again!!!
After some time, I will gather another group of friends and people from the city and near communities and travel to... well, We'll have two options:
1) Go east to join the MidBOS and create a new hope!
2) Go west to San Fran and Join the Shi for the glory of the "Emperor"!
Both trips are very dangerous and deadly (Deathclaws, Supermutants, Floaters, Aliens...) but post apocalyptic life is not easy.
I like Shi: they have technology, kung fu and a great ambition (a new empire!). There are hubologies, but they're not a great problem...or not?
