Injection sites

Is there anywhere I can't inject? Latest rise to a technical challenge - in a bar, by candlelight, balanced on a stool.
I would have preferred to do this discreetly at a table but we'd left our reservation too late and the Jill Sobule concert at Joe's Pub was sold out. I guess I could have gone to the restroom but that's a trek and pretty gross, and after the great hypo incident I prefer to actually order the food and count the carbs rather than guess from the menu. (Evil tiny cute rolls).
I had to count the clicks on my Pen because it was too dark to see and avoid the people jogging my elbow while injecting but mission was successfully accomplished and the concert rocked too.
