Larger-than-life gas-guzzling monstrosities with names like Maximum Destruction, Air Force Afterburner, Grave Digger, Iron Man, Monster Mutt, King Krunch, El Matador, Destroyer, Raminator, Rammunition, Bounty Hunter, Stone Crusher, Bad Habit, and ? my personal favorite ? Teenage Mutant Ninja Turtles will jump, race, ram, crush, crunch, and engage in other hard-to-describe “freestyle” feats at the United States Hot Rod Association’s Monster Jam this weekend. Trivia: A former property of Live Nation’s motorsports division, Monster Jam is presently owned by Feld Entertainment, a company founded by promoter Irvin Feld (1918-1984), who, among other accomplishments in his career, established Ringling Bros. and Barnum & Bailey Clown College in 1968. $19-$147, 7:30pm Sat, Jan 15; 2pm Sun, Jan 16, Alamodome, 100 Montana, (210) 207-3663, sanantonio.gov/dome.
