On our way back from Wyoming, we saw at least 10 cars in the ditch from slippery conditions on I-80 in Nebraska. The worst was an overturned red Dodge Ram 1500 on the ramp from I-80 EB to US-75 SB in Omaha. The truck was sitting upside down, resting on the barrier, with its roof caved in. Did anyone else see/hear about this?
