What sort of town doesn't have Spock ears for sale around Halloween??

THIS town, that's the sort.  Podunk little college town 45 minutes from ANYWHERE, Pennsylvania.  Harrumph.  My latex Spock ears from a few years ago have decayed into dehydrated squiggles of sadness and broken dreams, so I thought, "Perfect timing!  All the stores have Halloween stuff!  I'll just get another pair!"  Except THERE ARE NO OTHER PAIRS.  In fact, I couldn't find ANY sci-fi-related costume items in any of the stores.  None.  Zip.  But I did find all sorts of "sexy" costumes and costume accessories.  :/ 

So there's that.  The plus side?  If I were to blond-ify my hair, I could totally throw together something like this and go as Samantha Carter from Stargate:

  In fact, it could be an awesome guerilla-costume, because a lot of people probably wouldn't even realize I'd dressed up (though the hair would be a giveaway).  Once I thought of it, I was surprised that I hadn't thought of it sooner.  Sam Carter is awesome.  Question is, do I want to blond-up my hair?  I don't know if a temporary blond-ing would work very well, and it can be damaging to the follicles.  Plus, I just touched up my color a couple weeks ago.  Hmm.
