It can be bad here in central Texas... not only hills and valleys, but rather thin topsoil that saturates with water very easily. And of course, we have been getting a lot of rain... San Marcos, about 60 miles south of here, has received about 15+ inches of rain since last Friday. And just heard that they're getting about 3"/hour more right now, and it's heading this way.
Really....my weeds are dying....the trees are fighting over dogs!
