Maybe tax soda pop and candy?
Among the ideas the state Parks Board threw out to fill the hole when their gas tax funding for trails goes away: Diverting sales taxes from sales of boats and off-road vehicles to trails; imposing a new tax on sporting goods to fund recreation; and slapping an extra tax on soda pop or candy, which 19 states already do. Another idea was to tap a federal funding source that now goes to Idaho Fish & Game for their boating facilities, though the board acknowledged that'd create a new funding hole at Fish & Game. Other ideas included raising Idaho's motor vehicle registration fees by $3 specifically for recreation, and giving parks a share of lottery proceeds, which now go to schools and the state building fund.
