No, don’t worry: S.H.I.T.S. is an acronym and stands for “Saturday Hash in the Summer“.
No, you really don’t have to worry: Hash has nothing to do with smoking. Or cookies, for that matter.
It’s short for a worldwide social running club, the Hash House Harriers. A foot (or feet) is its logo. Runners follow a trail marked in chalk or flour and when they find the right way to run they shout “on on“.
Cee was asking for feet for her Black&White Photo Challenge. Feet she got. More feet can be found here.
