Stay safe out there everyone!!

Wildfire smoke continues to fill in across northern IL and northwest IN and is causing very poor air quality in addition to reduced visibilities. If driving make sure to slow down and use your low beams so others can see you.

The Illinois EPA has recommendations on how to stay safe during periods of very poor air quality which can be found in this PDF (https://document.airnow.gov/air-quality-guide-for-particle-pollution.pdf). Make sure you also check the latest air quality information and forecasts on AirNow.gov!

If it looks and smells smoky outside, you’re not imagining it.

Smoke from Canadian wildfires has moved into northern Illinois, resulting in Very Unhealthy air quality across the Woodstock area as of Thursday morning.

Current guidance recommends that everyone reduce prolonged outdoor activity and heavy exertion. Active children, older adults, and those with heart or lung disease, including asthma, are advised to avoid prolonged outdoor activity or heavy exertion.

Supporting local is more important now than ever. Whether you choose our business or another locally owned shop in town, we hope you'll continue to support the businesses that make Marengo such a special community.

And this isn't just about automotive shops. It's about supporting our local gas stations, grocery store, insurance agents, restaurants, laundromat, hairdressers, barbers, and the many other small businesses that serve our community every day.

Every dollar spent locally helps support local families, creates local jobs, and keeps our town strong. When local businesses thrive, Marengo thrives.
