There are several big .NET development conferences, such as VSLive, DevConnections, SD West, etc., but I am finding a lot of value in some of the smaller scale local conferences that have been cropping up over the last few years. I have enjoyed some of the smaller conferences such as devLink (http://www.devlink.net, Nashville, TN), CodeStock (http://www.codestock.org, Knoxville, TN), and CodeMash (http://www.codemash.org, Sandusky, OH). These conferences are considerably less expensive ($100 or less), and last just 2-3 days and are (arguable) suited better for people who aren't interested in traveling to attend the conference. Note that these are general .NET developer conferences, not marketing-driven MSDN one-day events or tightly scoped training events.
What other "local" conferences are going on around the country?
