MiniCon, a science-fiction and fantasy convention, is coming up on April 2nd through the 4th. Although there are no LARP-specific events listed, there are numerous role-playing opportunities, including a gaming room that will be open twenty-four hours a day.
In addition to having a chance to get in some basic role-playing, there are panels that LARPers of every type may find interesting, such as the "Costume Doctor" panel, which focuses on fixing costume issues, perhaps of the type you found while preparing for spring.
And, of course, there's the chance to meet new friends. There will doubtless be those who are interested in LARPing for the first time, or newcomers to the area who would love to meet fellow LARPers and learn about the local games.
