My dad used to pick some up when he took our dog for a walk, and the way I would realize he had done so was by my suddenly feeling queasy due to the smell.
I hope you get the chance to try it sometime, but if you don't know that it might also not be a bad thing :)
Long story short, the claims get much longer and restrictive through the application process. The example you asked about is currently undergoing a non-final rejection, and the claims will get much more restrictive in further iterations (assuming that the application has actual merit somewhere in the original dependent claims)
