Happy National Hammock Day! Whether you're napping under the shade of trees, enjoying the ocean breeze, or simply taking a break with a good book, this is the perfect opportunity to "hang out" (get it?!) in nature. Hammocks are allowed in most national parks, but each park has its own rules, so do your research before posting up. #NationalHammockDay #HammockDay #Hammocks #NationalParks #HangingOut #NPS #Parks #ParkTrust #USForestService #NationalForest #Tongass 📸: U.S.ForestService Image: Hammock hung in a campsite in Tongass National Forest
