a) You guys have far surpassed the creepy factor with your astonishing Googlestalk skills. For resourcefulness, I commend you a-holes.... for sheer inappropriateness and spook actor, you guys should seriously receive an award.
b) Like most 24-year-old women, Lena seems almost (resourcefully) intrigued & flattered by this onslaught of attention. She must really be dedicated to that Grand Trip, boys, and speaking as someone who's rafted enough class IV & V (non-commercially) in her day, you should consider inviting her along on your permit for that attribute alone.
(Lena, this whole thing reminds me of something one of my girlfriends said when we were joined by a certifiable nut in a bar in our early 20's: "Sure, he may be an axe-murderer, but he sure does seem to enjoy buying us drinks!")
c) You horny Buzzards haven't changed a bit after all these years! I haven't decided whether to be disturbed or entertained by this small realization yet, though.
