So as an ice fisherman, and in defense of ice fisherman, I have a comment.
1. Ice fisherman drill holes in the ice to fish. There are no holes anywhere in this picture.
2. The tents in the picture are not ice fishing tents, they are camping tents. Ice fisherman use tents that are better quality and can stand up to harsh conditions. No ice fisherman would use a camping tent- it would get blown right over.
3. There's a banner frozen in the ice. The banner reads
BAUER. Bauer is a hockey company:

If you look at their website you'll see that their logo is the banner in the picture. This debris was left by a hockey gathering, not ice fisherman! It's unfortunate how quickly you guys jumped on board the bandwagon to blame fisherman.
