Previous tenant just bailed out (earlier than contract), so place is back up
for rent, and the lawn needs some work/help/prayer.  Since it's about 15
miles away, driving over every other day to switch on the sprinkler is not
appealing.  Did I mention that "lawn" is a 4-letter word?  :-)

Cheers,
-Neil.
