This week's snowfall reminds us that snowmobiling is one of New York state's lucrative pastimes. A study done by the State Office of Parks, Recreation and Historic Preservation in 2003 estimated the positive impact of the sport on the state's economy at $875 million.

That being the case, it is important to take the fullest advantage of the activity.

While people undeniably like to get out and climb aboard their snowmobiles for a day or evening on the trails, not enough of them are registering their snowmobiles. The State Snowmobile Association was imploring snowmobilers to register early to capture as much state money as possible for trail grooming.

New York state offers a very compelling deal for snowmobilers: It costs $100 to register a snowmobile, which is required by law. Of that $100, $10 goes toward the Department of Motor Vehicles. The rest goes toward a dedicated Snowmobile Trail Fund, to be distributed through grants to build and maintain trails.

But, if the practitioner joins a snowmobile club, the cost of registration is only $45. The clubs still are eligible for the grants.

Registering as early as possible was recommended because the trail grants were available only from money collected before Dec. 1. The association was hoping for a rush because, as of Nov. 15, only 24,000 snowmobiles were registered, compared with last year's 130,000 registrations by the end of the season.

Without proper grooming, trails can become rough quickly. With less-smooth trails and the high cost of fuel to get to the trails and then ride, fewer snowmobiles may be out this year, and the economic impact on the state could be felt.

And, of course, the chance that renegade snowmobilers running roughshod over areas where they are not welcome is also a possibility. The responsible snowmobilers get a black eye along with the lawbreakers when this happens.

Joining a snowmobile club is a good idea, even without the possibility of grant money being available for grooming. The clubs foster conscientious use of the vehicles and help provide safe trails without trespassing where the snowmobiles are not wanted.

Being out on the trails can be a very rewarding and enjoyable experience. Responsible sledding also helps cut down on the risk involved. We see far too many accidents on snowmobiles resulting from drinking or riding off the trails. Joining a club will discourage those perilous activities.

So, even though the deadline has passed for joining a club and getting the money into the important dedicated trail fund, it will save you money on your registration -- and it could save your life.
