Good point!  There is about 30=E2=80=99 of back to front slope in my =
lot. Fortunately, and really just by accident, the zones pretty much run =
back to front and I blew them out in order the first few times, then in =
reverse order to be safe. I think I=E2=80=99ll be ok this year, but =
definitely something to keep in mind for the future!
