The fireworks were shot off the pier in Mackinaw City. We were lucky enough that our hotel room faced the lake so we were able to place our chairs on the front lawn and had the convenience of no traffic to fight after the show.
We noticed some odd floating lanterns that seemed to be released randomly. Apparently, it was something that could be purchased and lit then they float up into the sky like a balloon. One happened to land on the road right in front of us right after the fireworks show was over. My husband went over to see it when it fell on the road. He said it was made of some kind o thin paper. Perhaps it is made to be biodegradable.
