Heading to U.S. Nationals

I just checked the temperature in Harbin and it's not suppose to get above 0 degrees F in the next week. In contrast, in Lake Geneva, Wisconsin, the temperature will struggle get below freezing for any appreciable length of time this week. That's bad because my sons and I are headed there to compete in the U.S. National Snow Sculpture Competition. Without cold temperatures our block may just melt before we can make anything out of it :(
