If so, someone should consider renting time on as many of those billboards as they can. Then, they can flash all sorts of messages that Dems would prefer NOT to see during their convention.
For example---"Beam Me Up, Scotty!"
About a year ago, a former Planned Parenthood official wrote a book about her experiences in the employ of that abortion provider. She tells the story of watching an abortion. Before killing the baby, the doctor joked "Beam Me Up, Scotty."
Imagine a billboard with the words "Beam Me Up, Scotty" on it, followed by a URL to a website with much, much more info.
I'm just sayin...
