CELEBRATE MEMORIAL DAY WEEKEND RESPONSIBLY! 🙏 Each year, thousands of San Diegans and tourists celebrate the holiday weekend at our local beaches, bays and lakes. ☀️ It’s the unofficial start of summer and many choose to enjoy it near water. 🌊 Please remember we can all do our part to keep our public spaces clean and safe. Here are some ways you can help: ✔ PREPARE: Bring foods and beverages in reusable containers. Bring trash bags to easily dispose of litter. ✔ DISPOSE: Dispose of any waste in a covered bin and recycle. ✔ CARE: Be considerate of others, including our wildlife and pets, by not leaving anything behind. THINK BLUE SAN DIEGO 🌊💙🌊
