It’s all about the grandparents at Thompson Farm’s Grandparents Weekend. Grandparents get in free with the purchase of paid child admission, opening the door to the all-new Norma’s Play Area. Enjoy the petting zoo with over 35 farm animals, a corn maze, hay wagon rides, animal feedings, food trucks and more! Thompson Farm has been named Hulafrog’s Most Loved Farm two years in a row, so you’re sure to have a great time while celebrating the joy of being a grandparent. Thompson Farm, 100 Brickyard Place. Saturday-Sunday, 10 a.m-6 p.m. Free. www.Thompsonfarmandnursery.com
