Thanks Hal, I know they are not Blackberry. I was just using that as an
example, trying to explain them to Travis.

Dig up a root and see if it has a bulbous like rhizome that connects
to others just as ugly. That is probably pipe briar, not blackberry.
The only cure I know is dig up the roots. Blackberry can be a PITA,
but can be killed with careful applications of Roundup, I don't know
of a herbicide that kills pipe briar.
