❄️Small Business Saturday…Take 2!❄️

❄️ Small Business Saturday… Take 2! ❄️
Last weekend’s snowstorm may have slowed down shoppers, but our small businesses deserve the support they missed out on, so we’re joining Downtown Crystal Lake / Main Street and several surrounding towns / Chambers for a Small Business Saturday Re-Do on December 6th!
We’ve created the below graphic you’ll see circulating around town and we’d love for you to share it, spread the word, and encourage our community to shop small not just on the 6th, but all season long. ❤️
This is a perfect chance to revisit your favorite local spots (or discover some new ones!) and show them a little extra love.
Let’s rally together, McHenry, and make December 6th the Small Business Saturday our businesses deserved last weekend. 🛍️✨
