Third try, finally got inside the old Plz Fv Hndrd hotel. No roof access, and not much to see beside bare floors, skeletal walls, some tools, and Tim Hortons cups -- although my exploration was somewhat curbed by the onsite security. I think I was playing cat-and-mouse with him/her in the stairwells at one point -- though they didn't call out, so maybe they didn't hear me.
