Did you know that eating burgers can help fund scholarships for summer campers?

All you have to do is join us for a fundraiser at C Burger in Boulder on May 4, 11am–8pm. 25% of proceeds, both in the restaurant and from online orders, support YMCA Camp Tumbleson Lake. These funds allow us to provide financial assistance to under-resourced campers and ensure equitable access to nature. Bring the family, enjoy a burger feast and make a difference for the young people of Colorado.

📌 C Burger, 921 Pearl St, Boulder
