So, continental US, excluding maybe Nevada and New Mexico (because desert).
> you should have antibiotics on hand at all times.
So, here is a problem: in US, antibiotics are prescription-only. And no doctor would prescribe antibiotics preventively. They will prescribe antibiotics after a tick bite, but you need an office visit (or online office visit). The only way to get antibiotics preventively is to stash some after a tick bite, or simulate symptoms over a video call.
TL/DR: if you are in US, you're fucked.
