California has more than 100,000 miles of motorized trails and has invested over $250 million in funds raised from user fees in the trail system. The state parks department even has a special division for off-highway vehicles (OHV), which conducted a study in 1993 of the economic impact of OHV recreation in California, and discovered the following:
- Users spend $1.2 billion each year on vehicles, equipment and trip-related expenses.
- This spending results in an additional $3.0 billion of annual economic activity and supports 43,000 jobs statewide.
- The average OHV-using household spends $3,500 per year on expenses related to their OHVs.
- Snowmobiling is the most family-oriented OHV activity, as 55.3 percent of snowmobilers came with family members.
