I don't believe we have any upcoming trainings in Atlanta, unless you are speaking about our Ruckus University Dog Days events.
We do have a Dog Days event coming up October 14 in New Orleans (closer than Sioux Falls!). You can register here: http://a030f85c1e25003d7609-b98377aee...
Otherwise, what sort of training are you looking for? Everything we and our training partners offer worldwide can be found at https://training.ruckuswireless.com
