Looking around, I found a few interesting East Coast free events that are soon or in the future:
Maxim Karpov is giving a free Portal Development mini-Code Camp covering SharePoint, DotNetNuke, and Portal Framework ASP.NET 2.0 in Charlotte, NC on August 20.
The original New England Code Camp is starting again on its 4th iteration: Developers Gone Wild! at Waltham, MA on September 24-25.
If you are near any of these events, check them out.
