A woman dancing nude on the top of a big rig held up traffic for two hours Monday morning, snarling the mid-morning commute for miles along westbound US-290. The bizarre incident began around 9 a.m., according to Harris County Sheriff's Dep. Thomas Gilliland, explaining that a naked woman wandered into traffic on US 290 near Huffmeister, causing a three-car pile up. Shortly after, she climbed onto the top of a large, 18-wheel big-rig, where she remained for more than an hour. Camera footage from bystanders captured images of the woman screaming at authorities, before fire fighters finally coaxed her into a ladder truck basked around 11 a.m.
