It's National Pancake Day, and IHOP is offering a free short stack to its guests. In return for the buttermilk flapjacks, you'll be asked to consider leaving a donation for Children's Miracle Network hospitals and other designated local charities. National Pancake Day has raised nearly $8 million for charity since 2006. The offer is good from 7 am to 10 pm. For details, visit ihoppancakeday.com.
