I've tentatively arranged to do a CentOS Dojo/Meetup in Oak Ridge Tennessee, on Tuesday, September 5th. This will be held in conjunction with the local LOPSA (League of Professional System Administrators - https://lopsa.org/ ) and ORNL - Oak Ridge National Laboratories.
If you are in the area, and will be able to attend, please get in touch with me, as we'll looking for a couple of speakers. ORLN is a big OpenStack shop, so I expect to see some OpenStack content from them.
We'll be announcing more information here as we have it, and look forward to seeing you in Oak Ridge.
