I started in the early 90's. I think most of the buildings have either been torn down or completely remodeled, or are new. Widtsoe, Nichols, Fletcher, HFAC, the weird bridge to the JRCB and the building itself, KMB, McDonald (old health center), ESC, SFLC , DT, Heritage, Helaman. On the new side, there's the life science, engineering, SFC, music building, HBLL and TNRB additions, Hinckley, Provo High School, etc. etc. The list goes on and on. My son started FSY at BYU today and it would hardly be recognizable to someone who hadn't been back in 30 years. Oh, and no Provo Temple and a totally different MTC. Yep, I'm one of the old geezers now, I suppose.
