Sounds like my lawn; I think Florida has every weed known to man and then some! Our lawn has large areas of crabgrass and all kinds of weeds; one in particular that makes me crazy. I got an ID for it this year (Tropical Chickweed - Drymaria cordata) and it has little sticky seeds that cling to everything! We have a Golden Retriever and his long fur gets covered in those sticky-ticky little things!
