I'll try posting a few screenshots from the event here:
Rocking out with DJ Phoenix on the Founders Fall Univ. Dock.
Ladies' Swimsuit Competition
Solving the Player Mission, run by Crash Positron's Catgirl Brigade, Tahquitz, Steelhelm and others
Fireworks on the Docks!
End of DJ Phoenix's show, with torchlit remembrance of those we've lost.
And final fireworks as the Summer Block Party ended.
