The state system: registration fees, leased farmland, volunteer clubs

1976 — present

How it is paid for: Indiana's snowmobile trails run on the riders' own money. The DNR's program manual states that the trails program "is mostly funded by snowmobile registration fees paid by Indiana's snowmobile owners," and the cooperative agreement for Allen County's trail states it without the qualifier: "Funding Source: Snowmobile registrations 100% by Indiana statute IC 14-16-1-30." Law enforcement for the trails, and the snowmobile safety course, are funded from the same fees. No general tax revenue stands behind the system in the documents consulted.

How it is built: The legal authority is IC 14-16-1-26, under which the state designates trails on private land. Almost the whole system is leased farmland and woodland: a local club — which must be an Indiana nonprofit corporation in good standing — selects the route, negotiates leases with landowners, builds, signs, grooms, and insures the trail, and takes it down again in the spring. Since 2007 the clubs have managed the leases directly. The state pays a club $1,500 in pre-construction costs and $65 per mile for construction and maintenance, reimburses the landowner leases at $75 per quarter mile or $2 per acre, and supplies the groomers, signs, and posts, keeping the equipment's records and paying for major repairs. The Indiana Snowmobilers Association stands between the clubs and the state: in the manual's words it "represents the interests of Indiana's snowmobilers, works with the DNR to improve the Snowmobile Trails Program," and works "to organize snowmobilers into effective, responsible clubs, capable of making long-term commitments to the trails program."

The season: A state designated trail may open only between December 1 and March 31, and only when the club posts it open — snow, not the calendar, decides. Clubs work a longer season than riders do, from November 1 to April 15, to construct and deconstruct the trail. The rules printed on every state trail map are the system's fragility stated plainly: all snowmobiles must be registered; wheeled vehicles are prohibited at all times; and leaving the marked trail is trespassing, for which a rider "can be prosecuted." A trail system that exists by annual permission of dozens of individual farmers is one revoked lease away from a gap, and the maps say so.
