Somehow I forgot to post this on the blog the other day. Apologies for that and I will make up for it somehow.
Thursday night I decided I wanted to finally try an In-N-Out shake, as oddly enough I've never had their shake. So we stopped and decided to go in an get a #.
Turns out that was a mistake. As the first "official" duplicate # is now 29. Not sure if it should be counted. I took it as a sign that I should never have an In-N-Out shake again (not to mention I wasn't impressed).
