YES, had this e-mail romance going on for almost 2 years, with a girl from N. Mexico (Norteña) then on a trip state side, i decided to drive to Monterrey from FLA, Spent about 5 days with here in an apartment she owned , it was great, like a honeymoon. didnt work out later because of the distance between us, but still write once in a while.
As i'm more of the home body, its hard to find compatible people in person, by net, you can get to know a person a little more before meeting in the "real" world. I would do it again.
