As for hotel prices, not sure if they went up or not. Highly doubt they have gone up, its Bemidji (not that big of a town) and there are a lot of hotels to choose from.
As far as dirt track goes, it is stock cars. I don't have things confirmed yet on which class they will be racing (they are borrowing cars from local guys), and not sure exactly who will be sticking around.
you sound like you are working with the Rally. Thanks.
