What kind of grass is this?

[deadeye]

Any idea what kind of grass this is? Need to get rid of it? OK to leave it??? Seems to get pretty thick if not mowed for awhile.

Any takers on this one?

Could it be Japanese stiltgrass?

Whatever it is you don't want it.

Looks like it could be nimblewill. Not 100% sure though. Sometimes id'ing grasses by just a pic can be tough.
