Good luck getting rid of them! When I lived in Oregon, you couldn't kill 'em with poison. I learned how to cover myself in denim when I would go trout fishing. The worst was getting the low canes wrapped around your ankle and the thorns working like a saw blade as you took a step. I also learned how to fish with ultralight spinning gear to get around the overgrowth since there was no room to back cast and working a long fly rod through the brush was nearly impossible.

We would primarily pick the berries along the railroad tracks where you could get to the edges of the bushes and just work down the line. The berries are quite large.

You'll have plenty for blackberry cobbler, jams, etc. even though you'll be competing with the raccoons and other wildlife.
