Maybe those of us with hand function are better able to sort our problems out ourselves, we have to be adaptable when traveling (especially cheaply) - willing to sit on the floor of an inaccessible bathtub to shower, crawl into a bathroom with a door that isn't wide enough, crap into a grocery bag on the tent floor because the outdoors isn't accessible enough to have a toilet.
The adaptation and improvisation we do may be a bit more physical.
The adaptation and improvisation required when traveling solo as a quad I imagine requires a different sort of adaptation. Asking for help. Certainly much harder than the physical stuff, but the improvise, adapt and overcome philosophy still applies.
