From a story last fall on Fox 6 News:

WITI-TV, MILWAUKEE — You’d expect solar powered water heaters to be a big deal in Arizona or Texas, but now is becoming a big deal in Wisconsin. FOX 6’s Gus Gnorski shows you why it might be a good decision for your house.

The 2008 Solar Decade Conference, where the story was taped, will be October 23-24, also at the Midwest Airline Center.
