[quote=@TheUnknowable][@shadowsaint007] We can make nighttime work, or we can just write it as us leaving the next morning, and spending the day in the Vault.  I've got an old Army truck (nuclear electric) so we can drive there.[/quote]
Mostly because if it's daytime, we can get Gabriel up and rested as well, so that's another fighter (a sniper) to the group. Not to mention that a daytime trip would probably be safer due to lighting and lack of nocturnal predators - but then daytime has its hazards.
