Is it too late to lay down a pre-emergent? I've been so tied up with work
and other stuff that I haven't had a chance up to now, but I'm guessing I
should save my money and just live with it this year (again!).

Most likely. Next year put premerg out early and get the edges along
road and drive even earlier. Blacktop areas heat up faster and seed may
germinate there before you put down premeg. I like to get it down
before forsythias bloom.
