Can it really be a year since the boys of Four Day Weekend began gracing the stage of Casa on the Square, cleaning up after the goofy can-we-please-end-this-run-from-hell Forever Plaids? Yep, it is, as ringleader David Wilke made sure this was known by handing out special FDW chocolate cakes all over town last week. What, you didn’t get one? Then make plans to attend the anniversary performance on February 28.
