Someone sat cross-legged in the middle of general admission during the headliner and then looked personally offended every time people nearly stepped on them. Bodies get tired. We understand. But if 800 people in low light have to navigate around you like a boulder on a hiking trail, you are no longer resting. You are infrastructure.
I saw this happen at a festival and genuinely thought someone had passed out.
Terrain is the perfect word. Human speed bump energy.
