The day had dawned crisp and clear, but by the time afternoon had rolled around... it was really still kind of ridiculously warm for fall. People could probably get away with not wearing a sweater, even.
Which made rather good weather for a picnic, convenient since that was the traditional way of kicking off the Fandom High Parents' (and assorted other relatives, friends, acquaintances, or sometimes even enemies, but that was harder to fit nicely on a banner) Weekend. So there were rows of picnic tables decked out in blue and yellow, laid out with just about any sort of foodstuff one could imagine. And just in case there was any lingering doubt as to the purpose of the picnic, a glittery banner (Petra's work, naturally) adorned the registration tables:
