its become a little bit of a problem here on Lake George in NY. it has even sparked a letter writing debate to the local paper between some lakefront owners and Jeff Goldberg, owner of Fish307.com. the problem is that the landowners are aiming the ice eaters out instead of up, eroding the ice from underneath and weakening it, sometimes a long way out into the lake. unfortunately you can't always see the weak spots, and it can get hairy.
one landowner has an ice eater, even though he has no dock. he claims he is trying to keep fishermen off his property. the problem with his argument is that there is public access nearby, so nobody is going on his property in the first place. he's just creating a man made hazard. its just a matter of time before someone gets hurt.
