Crabgrass at bay

It appears that the crabgrass preventer that I applied earlier this year has done it's job well! I have not found any crabgrass anywhere in the lawn, except for along the very edge along the road and in a few places along the sidewalk.

Young crabgrass (the light green in the middle) growing on the
 edge of the sidewalk.

Crabgrass along the road in my neighbors yard (not ours). The seeds
had better stay over there!

I'm very pleased as I was expecting that my tearing up the lawn last year likely spread a lot of crabgrass seeds around. If it continues that none grows in the middle of lawn, I'll be extremely happy. Our lawn is small enough that I can hand pick any that pops up as long as it's not in huge numbers.
