Fiesta Folklórica is featuring its final matinee gig (for this cycle) at Gist Hall today at 2 p.m. A presentation of Cal Poly Humboldt’s Ballet Folklórica, Danza Azteca and Mariachi de Humboldt, today’s family-friendly performances come with a forecast of vibrant dance, music and clothing from various folk traditions around Mexico ($10, $5 children). On a personal note, it’s my birthday, so wherever you find yourself, rest assured that I will be fat and sassy, and hopefully a little spoiled, as I roll into my early 40s with all the grace and élan of a burning Tesla.
