Though this thread is rather old, I thought I'd add to it. I was in the 28th for a short time in the early 80s with Capt. O'Brien as CO (RIP charming warrior - August 12, 2010 obit at: _http://www.legacy.com/can-ottawa/obituaries.asp?Page=Notice&PersonID=144782821). Sharing the armoury with the engineers was always interesting as was accompanying them on various exercises or beaver dam removal projects.
I discovered a 28 Med Coy Alumni page on Facebook, for anyone interested (_http://www.facebook.com/group.php?gid=4779524303). I was a little disheartened when the unit was renamed and moved to Hamilton, if memory serves me well (which it rarely does). I was equally saddened when the armoury on Lees avenue was demolished, marking the beginning of the end of an era. Last time I saw CFB Rockcliffe, it was fenced off and some of the building were being demolished.
