no doubt about it...DNR was definitely makin' some revenue. Seen the groups waiting at the park with officer Opie when I went by with the groomer. As I was turning around at Antonio's to go back 5 sleds left the Mobil heading north along 64. I love this sport as well as anybody, but if ya can't be respectful and follow the rules, don't look for any sympathy from me. I personally, have called the Ontonagon County DNR office complaining about noise #1, and not staying on the trail (more precisely, riding on private property), #2. On the Michigan DNR website it says: each snowmobile manufactured after July 1, 1980 and sold or offered for sale in the state of Michigan shall be equipped with a muffler, not to exceed 88 decibels as measured using the 2004 society of automotive engineers standard J2567. It also states that any snowmobile manufactured after July 1, 1977 shall be equipped with a muffler that does not exceed 78 decibels of sound pressure at 50 feet as measured by the 1974 SAEJ-192a. Pretty sure that means if I can hear your sled being navigated around the Mobil station a half mile away, I have a problem with you interrupting the serenity of the northwoods. It also surprises me that we, as snowmobilers, have any trail system at all, with all the off-trail tracks I see in the woods. There would be no possible way for a snowmobiler to know if they are on private property or where the exact boundaries to the Ottawa National Forest are (unless you are going to hire a surveyor to go with you)....and then there are railroad right-of-ways....it goes on and on. If you are registered, quiet, respectful, and STAY ON THE TRAIL, you probably will be very welcome here. If not...STAY HOME !!!
