|Notice the warning at the top "address is approximate"--No kidding!|
So after driving around for twenty minutes, in and out of a residential neighborhood that didn't look like a private club of any sort, I did the most logical thing I could do. I started asking random people in the neighborhood if the club existed, and then where it was. With the help of a few people, I eventually found the club, which was obviously a super-secret American Legion hall that had been located down a narrow dirt road in the woods before this neighborhood had sprung up around it. The cake was delivered, and everything was lovely.
So my further delivery advice is to triple-check every detail of locations that you don't know, and leave yourself some extra time if you've never been to the location. If you get lost you won't panic so much if you have some time built into your schedule!
