Questions about "#8-99: The Solstice Scar"

[Tarrintino]

So, I've noticed that there are 3 versions of this scenario out there.

Does this mean that this PFS Special event re-playable outside of Core Characters in PFS?

I ask because apparently, Paizo is running the same scenario again this year at GenCon, and I'm trying to decide if I should sign up to play it again there?

Although, if it's going to be offered at DragonCon this year as well, then perhaps I'll replay it there so I have an open Thursday evening to play a different game at GenCon.
