1. 29th annual Cardboard Boat Regatta
River Legacy sure knows how to make fundraising look fun. In this event, participants build boats entirely out of corrugated cardboard and hit the water at Six Flags Hurricane Harbor for little more than bragging rights and trophies, including the Titanic Award for the most spectacular sinking. The event will be 9 a.m.-4 p.m. Saturday. Admission is $8 at the gate, and a $10 wristband gets you unlimited rides on some Hurricane Harbor attractions. (The park will be closed to the general public.) For more information on the regatta, including building a competition boat Saturday morning for $60 with a kit, visit riverlegacy.org.

8. Jeff Clayborn
The Texas country music artist headlines a benefit for Animal Hope Adoptions, an animal rescue and rehabilitation shelter in Fort Worth, so there will be tunes like his break-out hit "Good Bar Attender" as well as animals that are looking for their second chance at being loved. The concert will begin at 7 p.m. April 26 at Fairmount Music Hall (formerly the Live Oak), 1311 Lipscomb St., Fort Worth. Admission is free but a $20 donation is suggested.
9. New Play Readings Festival 2018
It's like a playgoer's dream: a reading of a new play, followed by a discussion of said play, times three. Sandwiched in between are drinks and food, even dessert. The plays to be read include "Kill Local," by Mat Smart, who wrote Stage West's season-closer "The Royal Society of Antarctica"; "Sweetpea," by Dallas playwright and actress Janielle Kastner; and "Dust," by Nicole Oglesby, an Austin playwright who is a Fort Worth native and Haltom High School graduate. The fest begins at 1 p.m. Sunday at Stage West, 821 W. Vickery Blvd., Fort Worth. Tickets are $10 per reading, or $25 for all three. Or $50 gets you all the readings and dinner, too. 817-784-9378; stagewest.org
10. Kelly Willis and Chance Ray
Fort Worth's always been a little sweet on Kelly Willis, and it will no doubt show her some love at her free show at 7 p.m. Wednesday, April 25, at beer garden/bar The Yard, 3017 Morton St., on the western edge of Fort Worth's 7th Street district. The show is 21 and older. Ray is best known as the frontman for the Fort Worth band the Good Sinners. Willis has a new album, the Bruce Robison-produced "Back Being Blue," that is coming out May 18.
