We quickly discovered that Siri LOVES the beach. Not only could she splash in the surf but there was so much sand to DIG (and no one yelling at her to cut it out!) She can really move the earth when she puts her mind (and both front feet) to it.
Sadly, our days at Vandenberg were short-lived but we made up for it by getting re-assigned to Colorado where Siri discovered the joys of camping.
