From what I can see on Google Street View (dated 9/2014), there is no 30.06 posted on the exterior doors. The only other likely location would be just inside those doors on N. St. Mary's where the ticket office is located. The VIA buses are blocking the Commerce St. side entrance on Street View however that is not a public entrance.
I don't recall seeing 30.06 the last time I was there. However that was several years ago and prior to the current business. The current business is operated by the owners of Sam's Burger Joint FWIW.
