It has never been easy since back when me and my friends would sneak in 20 years ago. There was always security patrolling and you needed a crowbar to pry open an entrance since they constantly patched up previous entrances.

It’s not the same at all anymore though, been bought out and repurposed as a stupid Halloween thing. Though I hear it’s only one building they renovated for that, so in theory you could sneak into one of the other buildings for the classic urban exploring experience. Idk for sure though, haven’t lived around there for 2 decades, just going by word of mouth
