Superman's Dressing Room Traditional Cache

This is a park and grab, but there may be muggles around. It is a magnetic cache with log, (BYOP). The hint is in the name of the cache. There are two places on this property that it could be, but it is in the one closest to the storefront. Hidden with permission.

You're looking for a place where Clark Kent might be able to change in a flash. Well, it's not the whole experience, but it's close. You're looking for a magnetic container and depending on the time of day, you will probably experience muggles. If you're smooth about it, you can do it. The store manager is aware of it, but be cool anyway. Park and grab.
