The Arkansas Literary Festival, held this year from April 24-27, has released this year’s schedule, which includes appearances by Mary Roach, Mona Simpson, Kevin Brockmeier, John Lewis, David Finkel, Victor LaValle and presentations on lucid dreaming, paleontology and Arkansas legends from Johnny Cash to Donald Harington and Brooks Robinson. There will be concerts, art shows, open mics, dinners, parties and collaborative LEGO-building functions. Only a few of these things require tickets, and you can get those online right now today.
