Was part of that mess, avoided crashing into the Benz in front of me by throwing it in reverse. Couple inches to spare! Lol ours happened headin up right at Merrill avenue in Wausau. . I’d say 25 car pileup but was able to back up to take exit , got back on at the farm and fleet only to see another pileup that you see in picture above. Worst I’ve ever seen first hand. We were very lucky. Had a buddy leave Chicago west suburb to eagle river and took around 9-10 hours. Heard there were some injuries but not sure of severity’s.
