Agility addicts are such superstitious beings. You'll often here, "This is my lucky Q shirt!"
Anything that happens before, during or after a run can be taken into account. For instance, one might think, "I got a Q the last time I wore my blue silk undies". So, and agility addict might wear those same silk bloomers until it's effectiveness wears off.
Favorite shoes, leashes, socks, even treats.
One of these days- I'll find that magic pair of undies, or socks, or treats, so that the Q's will start rolling in! But, since I don't have that---I have my friends!
