In the total of fifty minutes I spent waiting at bus stops today, I managed to get two full juggles in a row (each of the balls goes from the start hand to the other hand to the start hand to the other hand) and a couple just juggles. It's fun, and bus stops are the perfectplace to practice - the plastic shield prevents you throwing the balls forward, the ground slopes towards you sop when you drop they're easy to catch again, and there's enforced idle time.
