For my birthday on Saturday we celebrated with a hike up Mt. Monadnock. Audrey did a great job - she sat happily in her pack on Chris' back making happy noises, smiling at the other hikers and babbling the whole way.
When we reached the summit, Audrey took a little snooze (it's EXHAUSTING climbing a mountain).
Kudos to Chris who carried her on his back the whole way and still said it was "easy".
