Philanthropist Cindy McCain spoke Tuesday night in a free event at the Dole Institute, 2350 Petefish Drive.

Stay indoors

Today will be mostly sunny, but the cold isn’t going away just yet. A morning low of 27 will improve gradually to a high in the low 40s this afternoon. Keep your eye on the four indoor events below to stay toasty, and save your energy for the 20-degree jump in temperatures coming tomorrow and beyond.

For the sane

Amid a changing social landscape of connectivity and communication, the legal and societal landscape of what is meant by “free speech” may be shifting as well. Or, in other words, how do you legally deal with the trolls in the comments? Find out at 7 p.m. at The Commons in Spooner Hall, 1340 Jayhawk Blvd., when Kansas University hosts the free panel discussion “Data & Democracy: What is Free Speech in the Age of Social Media?” The panel will be moderated by Deanell Reece Tacha, the Duane and Kelly Roberts Dean of the School of Law at Pepperdine University, and a former faculty member of the KU School of Law.

For the not-so-sane

If a veterinarian posing as a doctor, a race-horse owner and his friends struggling to help keep a sanitarium open is more your style, head to Liberty Hall, 644 Massachusetts St., at 7 p.m. for the next installment of Marx Madness, “A Day at the Races” (1937). A little trivia: Groucho’s character was originally named “Quackenbush” but was changed to “Hackenbush” over fear of a lawsuit by a real Dr. Quackenbush.

Class act

At 7:30, in another free panel event, the Dole Institute, 2350 Petefish Drive, will host An Evening with Cindy McCain. The philanthropist and American businesswoman will discuss her experiences as chairwoman of Hensley & Company and her extensive work with a number of major charity organizations, as well as share some stories from the campaign trail. More from our previous post here.

Open your ears

If you prefer music to politics, you might want to check out the KU School of Music’s choral presentation “Joy of Singing” at 7:30 at the Lied Center, 1600 Stewart Drive. The concert honors the late James Ralston, a professor of choral music for more than 30 years. Tickets are $8 for adults and $6 for children, seniors and students. Call 785-864-2787 or visit lied.ku.edu.

Or not

Finally, speaking of music, Scott Stapp, founding singer of rock band Creed, will bring his solo show to the Granada at 8 p.m. Doors open at 7. That’s all we’ll say about that.
