Does anyone who went to Commerce High in the late 40's remember crossing Walnut St. to the Annex? I remember going down in the basement of the main school and walking through a tunnel or hallway to get to the Annex on Walnut St. Which means it ran under Walnut St. We could also go outside and cross over that way. Our locker room was down there somwhere. I've tried Facebook, and searched the WEB but can't find anything to confirm this. Anyone know what I'm talking about? (beginning to think I dreamed it)
