Last one to post in this thread wins!

Afternoon guys been noticing my yard is lumpy and getting hard to walk on, so talked to a couple people in my area and they said it's earth worms and they will kill the grass.... ****!! now I gotta find a fix for that.
Mine got really bad with all of the rain. little eruptions everywhere. I dont think it will kill the grass though. Maybe find one of those water filled rollers.
