There are two great regional conferences coming up this year in Tennessee: devLink and Codestock.
I was fortunate enough to work with John Kellar on devLink from the beginning and it is great to see how large it has grown. This year it is back at its original (and best IMHO) location at David Lipscomb University in Nashville. It has also grown to three days (August 13th to 15th) with a still unbeatable price of $100 ($75 for early bird registration). It is also a little unfair to call it a "regional" conference, since it draws people from all over the USA and quite a few from outside the country.
Codestock in Knoxville on June 26 and 27th, is headed up by Mike Neel and is in its second year. For $25 you get two days of national thought leaders, talented regional speakers, and great open spaces to discuss topics you are interested in.
You can follow these conferences on twitter at @devlink and @codestock. Both events have out a call for speakers, so get your abstracts in now to be a part of these great conferences.
