FOR THE VEGANS: Bad vegan food can taste like food from a future, post-apocalyptic world where real food has been repeatedly recycled and tastes like dirt.

The first 100 people ages 16 and older receive a gift bag full of vegan products. 1419 W. Blackhawk St.; Noble Square. 10 a.m. to 4 p.m. Free.
