Painting in a National Park is fine, just as long as you’re not doing it on a rock or a mountain… A 21-years-old painter from New-York went on a trip to a series of National Parks (Yosemite, Crater Lake…) across 5 states, and she painted portraits in each park. She even took pictures and sent them to her Instagram account.
She was probably proud of herself. She has deleted her account now, but her pictures were copied and published by unimpressed internet users, who also reported her to authorities.
She is facing charges up to 5000 $ and a year in prison for vandalism.
