Niagara Falls Marathon

I have a friend who running in the Niagara Falls Half Marathon next month. I started looking at it, and thought it could be an interesting race. I first was only looking at the half marathon which runs along the river, and ends near the falls.
But then I started looking at the full marathon. The full marathon starts in the United States, crosses the border into Canada, runs along the river, and ends near the falls. Apparently it is the only marathon in the world that starts in one country, and ends in another.
The full sounded really cool. But then I started looking at the logistics. In order to run the full, I would HAVE TO be up there on Saturday to go through customs and stuff. So that would add the cost of a hotel room ($150-$200). We would also have to board the dog for a day or two.
After looking at the options, I decided it would just be easier to race the half marathon. We can drive up early Sunday morning, pickup my race packet, I can run the race, and then we can drive home that afternoon.
Though running across the border would be really cool! Maybe next year.
