Not sure; if she's young (almost certainly older than 19), she just may be brand new.  She's using the same name in her ads, too.

I think it's worth giving her a call and feel her out (no pun intended!).  If you get a good vibe, go see her with your running shoes on.  Do NOT go through with it if she's not the girl in the pictures.

Speaking of the pics....they look fairly natural.  Let us know, please!
