Quite a few years ago, myself and some coworkers happened to wear green shirts on a Tuesday. Coincidentally, it happened the next Tuesday as well. Ever since, Rika72 and I have been wearing green shirts every Tuesday. On very rare occasions has there been a mix up (usually after a long weekend), but good luck catching us without a green shirt on Tuesday! If you do find this cache on a Tuesday while wearing a green shirt (or anything green - shorts, socks, hat, jacket, etc), feel free to upload a picture! As well, you will become an official member of the Green Shirt Tuesday Crew.
