Looking for the perfect gift for Dad? The Academy of Natural Sciences of Drexel University is offering a special Father’s Day promotion, where dads get in free with one paying child on Saturday and Sunday, June 17–18. Spend a fun-filled day with Dad and see a towering T. rex, catch live animal presentations, and stroll through a tropical butterfly garden. Visit ansp.org for more info about activities and admission discounts for the rest of the family.
