Yep, blueberries too! You'll have to plant enough to share with the birds. But that arch thing is genius for blackberries, you can get in there and pick them without being scratched.
Once, I was in an old house, and the owners had planted an... arbor? Thing? that was about 50 feet long by about 10 feet high, and absolutely covered with the biggest muscadine vine(s) I've ever seen in my life. Right in their backyard.
