🚪 FOUR visits... and we have a feeling he still hasn't found every secret door. 😉!

It was wonderful welcoming actor Iain Armitage (Young Sheldon) back to O Museum in The Mansion.

Thanks for making us one of your favorite places to explore!

Had a great time meeting Ariana Hickerson and Lynn Emmert when they came for a visit! 🤩

☀️📚 Summer is the perfect time to get lost in a great story. Did you know... The O Museum is mentioned in multiple books! Don't forget to add them to your summer reading list.
