Only if you plan on going to SF for a vacation. Immaculate, I could see you falling for this gal as you have been the last few weeks. You live in D.C. -- I've heard there are tons of gals there. Why not just fish off your own dock and save $700?
That's too far to travel for a gal online who may or may not be something behind a pretty face on the internet. My guess? You'll meet her and she'll be cold as ice and you'll have a nice lunch down on Fisherman's Warf and she'll say her relatives want her to spend more time with them and she'll be gone.
It's a smokescreen ... devote your energies into where you live, unless you plan on spending a vacation in S.F., which is a great city. NEVER make a financial commitment/long trip for a gal you don't know, never, ever, ever ... they'll flake out. You know that, I know that, everyone here knows that.
