Dreamers and schemers alike are often found strolling through Harbury Park, a hideaway nestled between the high rises and corporate blocks of the careless city.  In the center of this peaceful retreat, existing there longer than the park itself, a small, bubbling fountain quietly circulates water from its glistening pool.  No one gives it a second thought.  No one, that is, except maybe those who happen to have a coin burning a hole in their pocket.  Unlike wishing on a falling star, or blowing out the candles of a birthday cake, a coin tossed into a fountain has no finality.  Or to put it a better way, what happens if the coin comes out?
