Well, the snow is melting (?), Spring is here, and puzzle season is coming to an end, at least for me it is. 
So here's my final puzzle to solve. I made it easy so even the youngest geocacher should be able to find the correct answer to this one.
But just to make it even easier to solve, I'll give you the first few letters to the puzzle's key 'cause that's just the kind of guy I am...a giver.
P = 0, Q = 1, ....
Now the puzzling part.
