To Plot or Not to Plot?

I actually did some plotting yesterday! I know, shocker, right?  I am the eternal 'pantser'.  But it actually came together better than I thought and it helped me iron out a few questions about the past of one of my characters.  It also helped me decide where to layer in some foreshadowing.  Soooooo, maybe plotting isn't such a terrible thing, LOL.  I will still cling to my 'fly by the seat of the pants' demeanor, but perhaps throwing in a little planning here and there.  It can't hurt right?
