Anyway, there's sort of four ways to go about getting to the strip from goodsprings.
There's the canon way, that the game wants you to go, talking to Beagle even though you can practically say every word of his diary to yourself without having to play it at all. Through nipton, talking to vulpes, to novac, to repconn test site to do Come Fly With Me (which is still probably the best quest in the game) then up to Boulder, then finally to Vegas.
There's the accelerated version, where you run from goodsprings through primm, nipton, novac, then straight to freeside.
There's the insane level one getting killed by cazadores route, heading north of goodsprings into hell.
Or, you can be really terrible, and sneak through Sloan, past black mountain, past a million deathclaws and to repconn hq.
So which do you typically do? I've got a habit of sneaking past the deathclaws, winning 40k at Vegas and then buying the implants, before wandering around aimlessly as I have no quests to do whatsoever
