Ugly Kid
Still Mildly Glowing
I brought up the power armor because they would trek across the country in sweaty, smelly, and just uncomfortable 2 ton suits of armor. Getting in and out to eat, puke, or to rest, would just take up more time and make the soldiers feel awful. And like Gorzan mentioned, there are mutants, monsters, raiders, and wars, going on for 2500 miles at least including their war with the NCR, by that point wouldn't they just find military and government property closer to home? Seems like such a hassle to go from coast to coast when there is almost 10 million square miles of land to explore in between. And if they were so desperate to go DC, why would they walk? I'd find it more believable if they flew in on vertibirds like the Enclave, Mathew says he copied the plans digitally and 30 years would be more than enough time for the BoS to start producing quite a few.
