I think with NW miles you can spend 35K and cobble together both Nome and ANC on AS, or just try to get Nome by itself on 25K. Would think renting a car for a day and seeing the "last train to Nowhere" might be neat. You could cover the whole road system, even.

Or just drink copious amounts of booze, said to be a local pastime.

Can't say I'm motivated to do a trip just to Nome, but with ANC or somewhere else as stopover it might be worth the 10K extra miles.
