Ask any guitarist and she'll tell you that all good musicians have callouses... So, for the last 36 hours I have been wearing stilettos to do everything--climb steep sf streets, water my plants, grocery shop, etc. Last night I went over to Oakland to do some laps on the cobblestone around Jack London Square, then I slept in the heels, just so my feet would get used to having them there. Afterall, I'll have to camp out in them, come October. I have no calluses yet, but if the blisters are any indication, I'm well on my way to being a "good musician."
