Looks like Wisconsin has lower than average natgas prices vs. rest of U.S.: https://www.eia.gov/dnav/ng/ng_pri_sum_a_EPG0_PRS_DMcf_m.htm

seems pretty comparable to the other colder parts of the country. (besides the east coast) The warmer parts of the US i'd imagine are less sensitive to residential gas prices.
