Is it appropriate to put "Southwest Florida" for an incall in the ad, or is it too broad?

Personal opinion, too broad.  Can cover from Tampa to Naples and generally guys ain't coming from Tampa down to Naples or Ft Myers and vice versa.  I would give a more specific location within a few miles

is generally what I would consider southwest FL but I'd be specific to cities and not a geographical area..

I agree. But I really wanted to reply just to say god damn, your smoking hot!!!!!!

If you'll be in the Naples/Fort Myers area, then I'm definitely interested. When will you be visiting? Although I'm based in Miami, I have a house on Sanibel so Naples and Fort Myers (and everything in between) works for me.
