Name: Marilyn, aka "Poly" South San Francisco Bay Area (Zone 9b) "The mountains are calling..."
We have some squirrels here too... I don't think they were a problem with the drip or netafim. The only problems they seem to cause are digging up my flower pots (to plant acorns), planting oak trees where I don't want them, and (possibly - not entirely sure that they are the culprits) moving or stealing plastic labels.
Evaluating an iris seedling, hopefully for rebloom
