So, they went down to the beach, and a very obviously drunk Spencer built a cairn (that's what the name for stacking those rocks is called KT and Spence). He was so proud of it, and KT was so proud of the picture she took of it, but neither of them know why people build them and why you shouldn't build them for your dumb Instagram pictures. If they knew anything, they would know that those are only to be built as markers for hikers to find their way if they have gotten off the trail or are lost. When you simply stack them for a picture and they have no purpose other than to try to get views and likes, they can destabilize the shoreline; increase the risk of erosion, and damage ecosystems.
bleeping IDIOTS.
