My Dad used to say, "There's no free candy in this country." So, I decided that would be a perfect name for this cache. This is a puzzle cache which must be solved to reveal the final coordinates. Do not go to the origin coordinates in Grace Lake... there's nothing geocache related there.
How many pounds of $3.53 per pound candy needs to be mixed with how many pounds of $8.10 per pound candy to make 7.539 pounds of candy that would sell for $5.99836981 a pound?
