I grew tired of having to fire up Internet Explorer each time I wanted to check on someone currently at Graterford. The PA DOC site shrugs off the thought of compatibility with non-IE browsers. Not surprising from an institution as unjust, overcrowded, and corrupt as Graterford prison.
Anyway, here’s a link I found that worked in Firefox: PA DOC Inmate Locator. If you know anyone at Grateford, I’d enjoy hearing from you.
