Here's a great idea: Copenhagen is building a new waste-to-energy plant that will have ski slopes on it. People will take an elevator to the top of the building and ski down one of three slopes. As the article says, they have the snow but not the hills.
I wonder if that would work in Normal. If there were a tall building that also had a large enough circumference, it might. We don't have snow all winter but we have a few good snowstorms that would do the job. The Copenhagen project is actually going to "mist rainwater" on the slopes to coat them, so that's their solution to keeping an even amount of snow on the slopes, I guess.
