FORT COLLINS, Colo. — Fundraisers for Colorado state parks say there will be limits on corporate sponsorships.

Proposed limits include no car repair shops, no NASCAR and no billboards. Fundraisers are hoping health care, fitness companies or trail snack promoters will step up to help pay costs for 42 state parks that are self-sustaining and rely on grants and user fees.

According to the Loveland Reporter-Herald, the Foundation for Colorado State Parks said at a meeting in Fort Collins on Tuesday that it wants to partner with businesses and brands that meet the character and values of state parks and market them in tasteful ways.
