On July 26, the Western Pennsylvania Linux Users Group will be showing both Elephants Dream and Big Buck Bunny at the Creative Treehouse in Pittsburgh, which will be followed by a 45-minute presentation/demo/talk and Q & A about Blender by Roland Hess (harkyman).
Details of the event can be found on the WPLUG wiki:
Any Blenderheads in the Pittsburgh area are encouraged to just show up. It would be nice opportunity to meet some new people.
Check http://harkyman.com before you leave, though, as the Creative Treehouse doesn't have air conditioning, and there is a slight possibly that the WPLUG people may move or reschedule the event if in fact it is hotter than the surface of the sun that day.
