it must be a regional thing.
where I live are many farms and acres and acres of land. roundup is a part of everyday life.
no one is going to trim around a fence with cows in it for 200acres of land. they ride around the whole perimeter and spray it with roundup. they spray their entire fields with roundup or similar before they ever plant anything. it's just very common to use it here. it's not a big deal.
up in the northeast and other places roundup is treated like a disease.
there are farms up there too though. maybe it's just most people on lawnsite live in bigger city urban areas instead of rural areas. i'm not sure.
