A longtime Marble Falls tradition continues this weekend. The Howdy-Roo chili and barbecue cook-off is Friday-Saturday, May 5-6, at Lakeside Pavilion. Money raised goes to the Marble Falls Area Volunteer Fire Department, Boy Scout Troop 284 and the Marble Falls High School Band boosters. Organizer Craig Schlicke told KBEY 103.9 FM listeners about it.
