Two sites have opened, making 24 for the month, 180 total: Sherwood, OR (SW of Portland, off S.R. 99W, 5 mi. W. of Jct. I-5/205); Madison, WI (nr, Jct. U.S. 51/S.R. 30, w. of Jct. I-90/94/S.R. 30).
As previously noted, Madison makes the Chicago/Twin Cities route via Rockford practical, year-round. Sherwood is an urban QC, but will serve those people coming up I-5 who will turn off I-5 before reaching Vancouver, WA.
