Like the "greatest kindness" question, I've seen too many to pick just one.  
Oh wait, I did pick just one for that question; I still can't for this.  
Here's just a few: 
<p>
King Gyrth organizing pillow-fights at the rained-out Peace, saying it was in 
fulfillment of his coronation oath; the charge of the Western knights at 
Pennsic 6; Caryl and Asenath wading downstream in their shifts, herding rose 
petals; the long walk through the black woods to the parking lot at Legends 
at midnight, with just a candle-lantern; the jongleurs singing "Rosa Vernans" 
in Memorial Hall; the first sight of the fort on the field at Pennsic 30; the 
songs and the faces around many a campfire; single, one-armed combat on the 
bridge at Pennsic 15 (or so); Grendel's Arm at the Beowulf event.  The 
memories keep coming, but I have to stop typing because I have five more 
questions to go.
