the tour was great, i was suprised that i didn't go through very much security at all to get in there though... anyway, the guy that showed me around was pretty cool, he introduced me to everyone there, including the supervisor, good looking lady who was very pleased to meet me. there were about trainees working while i was there. he showed me everything he does from down in the dark room to up in the tower, it was wonderful up there by the way. i suggest checking it out. everyone was kinda hanging out and not workin to hard, didn't look very stressful at all
