JLAB is having open house this Saturday, 4/21.

I have been there about a year now, but I dont get to go into all the restricted pits. It will be cool to get to go underground into the accelerator. The accelerator track is about the size of a race circuit track.
I remember the first time I went into the control room. It was sooo cool, It felt like CIA control room. There is a HUGE ass screen on one side of the room, with accelerator controls and stuff.
