It’s been a big mess for TxDOT crews to clean up in North Fort Worth overnight. Just past midnight, 911 calls started coming in about a slippery liquid spilled all over Blue Mound Road near Meacham Airport.  Drivers were swerving around it, nearly causing some crashes.  Turns out the problem was a slick of fecal material.  Investigators don’t know where it came from.  Perhaps a septic tank cleaning crew’s truck lost its load or maybe there’s a sewage leak in the area.
