no problem, I had the same problem in GD with the 'xdforums shoot tomorrow' that was posted around midnight on a wednesday (i.e. very early thursday morning) and meant thursday instead of friday.
I'll be wearing my Team AR15.com hat and black COARFCOM shirt (but it'll be covered up probably). I'll have at least my tan FAL with scope and bipod and g21c in a holster, if not my shotgun and scoped 10/22. My coworker's got an AR-15 and H&K 91 (semi auto g3 clone). We'll be hard to miss.
Not to mention I doubt many other people will be up there at 9am on a Friday.
