A little backyard grass update

The supina bluegrass planted last year has been growing leaps and bounds. I'm starting to wonder if it will even have been worth it to have planted more seed this spring. I guess time will tell, but it seems that with each passing week, the bare spots fill in more and more. Here are some photos taken yesterday:

And for the record: I never ended up putting any starter fertilizer down.
