Thanks fellas.  I took the latter tip to heart and removed the quotes 
and used .to_s

As for the [i], I'm iterating over multiple queries that have the exact 
same row count.  Therefore, I don't need to use each.  I do use each and 
each_with_index a lot.

(1..120).each do |i|
...
end

.. this suffices and allows me to count the exact number of iterations I 
need.  In cases where I don't know the row count, or the row count isn't 
the same count across multiple tables, I don't use the above.

Thanks.
