Several snowmobilers cut across my front lawn close to my house barely missing a spruce tree. I've tried to put up baracades to make them aware, but as soon as I take them down, the snowmobiles cut across again. It's loud, it leaves horrible tracks for others to follow, and my kids will no longer play in the front yard. I hate putting ugly stuff up as baracades, but what else can I do? I wrote the local clubs and no one responded. I called the police and they didn't care (I think the person I spoke to has a snowmobile). I don't have time to stand watch and see who is doing this. A few people are making snowmobiles look bad. Help!
