The Mesa County Sheriff departmentâs new contest to discourage âpuffingâ sends the wrong message. Puffing causes unnecessary pollution, filling your neighborhood with exhaust fumes in the morning when the cold temperatures keep pollutants closer to the ground. Dress a little warmer, go out and start your car, scrape your windshield and drive slower for the first few miles. Not only will you cut down on pollution, but you eliminate the opportunity for thieves to steal your vehicle. Awarding a prize of an automatic starter just encourages more pollution. Your neighbors will thank you for NOT leaving your car running. Have we all become so soft that we canât stand a little bit of cold? Buck up, Grand Junction! Our winter air inversions are not the time to add more pollution to the atmosphere.
