When seeing the area on TV, I had the same thought, Dot, it does look like there is a ditch there. which is not unusual here in FL, since most places don't really have a sewer system. I remember when I lived in PA, there were sewers on the side of the road for water from when it rains. But in FL, at least where I live, there aren't sewers but ditches along the sides of the roads for water run off, so it doesn't flood the streets.
Well, I'm sure between media/'sleuthers' this area will be video taped many times over......be nice to see how deep the ditch is & how tall the 'kudzu' is.
LOL...you *might* could hide a small car in this ditch if the kudzu is thick enough.
for anyone NOT engaged in the ongoing FIGHT w/'kudzu' ........one branch of this invader can grow abt. 60ft per year.
