...here are my two favorite stories about a more "TNG"-heavy convention:
1) It is 199-something, and I have just purchased my beautiful, authentic, hand-made bat'leth from a surly Klingon vendor...I am on top of the world, and am actively looking for someone to evicerate, just so I know the darn thing works properly...I am scanning for Fresh P'tahk, when I see them...three of them...Klingon warriors all...walking in almost a phalanx, if such a thing is possible in a group of 3...not one of them below 2 meters tall...striding...taking over the space they move in...eyes painfully forward...and the people in front of them...they cannot get out of the way fast enough...like livestock blindly following some instinct to be elsewhere...anyelsewhere...no false make-up...no turtle shell and paint...no...these?...they are from Q'onoS itself...surely of the Council...my vantage brings me eventually perpendicular to them...I hold my "leth "at ease" and lower my gaze...as they are directly in front, I say to the leader, "jaH tlhej quv"...I THINK he may have moved his head a fraction of a millimeter in acknowledgement...they pass, and now I can look more fully...but wait...there are three Convention-goers directly in front of my Klingon Brothers...oblivious...I hesitate to continue watching, but it is a ghoul thing...surely these three are on their way to die, with or without honor...closer, striding...closer...really close now...and my Main Man stops in his tracks, mates stopping behind him, waits for the them to notice, and says, "excuse me" in a suspiciously NOT Klingon voice or accent...then, off they go on their merry way...I was heartbroken...no limbs...no impudence?...killing where one stands?...
...that is a 100% true story...
...my second confirms, for both VOY and TNG, that the casts really enjoyed working and screwing around together (acting silly)...I have had the good fortune to meet a number of actors from both casts, and I asked each the same question, and got affirmatives from each...my feeling was that they were being sincere...nice to know about something so close and beloved to me...
