I'm here in California as well, and I sincerely doubt any large events will happen either. The state will relax quarantine for regular desk jobs surely before the end of the year, but I can't imagine they'd start allowing events where close contact with hundreds of people is unavoidable. Not before antibody testing is happening in the millions.

Not to mention that the demographics (old/male) for Eroica could mean that a breakout would be devastating if a carrier attended.
