You have already received some excellent advice, but let me
address travel north and south of the Lower 48.

Reasonably priced cellular Internet access is largely unavailable
from US carriers in Canada and Mexico.

Regarding satellite TV, Dish Network goes further north on the
west coast, and DirecTV goes further north on the east coast. We
use Dish Network. Going north from Seattle, our under-the-dome
rooftop antenna stops working a couple hundred miles north of the
border. Not much further north, and our Dish 500 18" dish stops
working.

We also carry a single-LNB 76 cm (30 inch) dish. When there is a
clear shot at the southern horizon, we can get Dish Network at
least as far north as Denali National Park, which is way north of
Anchorage. There is no DirecTV service in Alaska.

We are currently about 800 miles south of the US border, near
Mazatlán. Our 30" dish can pick up most of the transponders on
the Dish 119 satellite (we don't use anything on the Dish 110
satellite). Our traveling companions have a 36" dish, and they
use DirecTV. They can only pick up about ten stations. They will
be renting a Canadian StarChoice receiver from another park
resident shortly. StarChoice has great service from at least
Alaska way down in to Mexico, using just the standard small dish.

Hope that helps.
