Sounds like most are good to go with "Winchester".
So I think, IMO, that the location is set.

Now just the date or date(s)

Heard a few comments on late August.....

So are you guys going again in august like last year if so I might be able to make that.

No worries Dave . The weekend of the 24th-25th would be my best option for August. How about  mid to late June?

I'm also OK with mid to late June as well.
15th/16th or 22nd/23rd
Nothing says we can't have 2 Zillathon's this year......?

Chime in guys and let's get the date set so we can get reservations going.
I'm liking Half Moon Bay this year instead of Discovery campground.
