Seth's San Francisco, especially in the [LN] and [RM] fighting that I saw it in.
Also, stewcool's Tenebras RP, in NY, when there where plenty of people that simply wanted to blue message him.
Yue Fei's Citadelle.de.Quebec LN BS. One of my inspirations.
A random independent Rheinland BS. I expected to get shot. Instead, I got one of the most memorable RP experiences of my Discovery career. (I wish I could remember his name, but I am intoxicated right now.)
Eternal's Aurora pops into mind as well.
A few others exist and will be remembered as time goes by. (Since, as previously mentioned, intoxication.)
Edit: Yes, Jessicka's brother's order ship as well.
