I think that the solution is the only part that confuses me now.  I've 
done quite a bit of playing around with irb, which is how I got to 
understanding that I can't seem to do what I want (DRY) with the method 
I was trying to use (variables in an array).  What I'm trying to find 
now is if there *is* a solution that will work for my particular 
circumstances.
