Sorry for the last minute notice folks, but one of the local OWASP chapters (OWASP DC)is going to be meeting right around the corner from the King Street Metro (near the Motley Fool offices for those of you who went to Refresh there).
I can't vouch for the quality of the presentation because I don't know that much about this month's, but there's usually some good discussion of current events. OWASP is a much smaller meet-up than Refresh, but it may be of interest to some of the folks who have wanted more discussion about web application security. Hopefully we will be having more metro accessible meetings in DC and/or NoVA (it's long been a sore point for OWASP, and lack of venue has been one of the reasons we don't meet more often).
Bare bones info is 6PM, at the offices of Grant Thorton, 333 John Carlyle Street Suite 500, Alexandria VA.
