[Dsg-rich] RICH survey data

[Tyler Lemon]

Hello Marco and Kelly, 

Since the meetings will be in a conference room, I will also plan to attend to get a better idea of the survey data that is needed. 

That way I would be able to help more if there are more questions or more is needed after Marco leaves JLab. 

Best regards, 
Tyler

Hi Marco, 
It is in the Ted building, 2nd floor room 2559. The conference room is in the wing that extends from the main mechanical engineering office area. 
thanks, 
Kelly

That's perfect. 
Where is the conference room?
