Sure, I'm a vegetarian. And I breastfeed my baby. And yeah, that baby may have a tie-dye t-shirt or two. And this one time I was breastfeeding my tie-dye-clad baby in a park, and we were both barefoot, and there was a guy playing the didgeridu (didgereedoo? didgeridoo?)* nearby and another guy playing the African drum a little further away. And since you asked, yes, I've even been to Burning Man a few times.
But I am NOT a hippie.
*ETA: Aha! It's didgeridoo! Thanks, Adrian.
