There's already a road.......................not a great road, but it's doable in a rental car.  Anyway, it's a bit of a nostalgic site.  Lose the crappy chain link fence that surrounds it and establish some kind of information booth/plaque to explain to people what they are looking at and it will do ok.  Not going to bring people to Nome just to see it, but it will give them something to do when they get there.  Then figure out a way to buy/transfer the large dredge West of town to the public domain so that it can also be an informational/historical site rather than something plastered with private property keep out signs and you would have the beginnings of a "tourist destination".  

Mix those two locations with a museum, maybe a "pan for gold" money sink here or there and some gold nugget jewelry stores and bam, a cruiseship/tourist mecca.
