I'm from Citrus County not too far away from St. Petersburg. People always say to me when I tell them I'm from Florida "Why are you here?" lol I'm sure you'll get that too.
Oh, cool. It seems like there are a lot of us infiltrating the UK!
And as far as the comments, oh my god. I get that all the time, and I'm not even there yet! People find out I'm going to Scotland, and the immediate response is, "...Why?" Normally I get a funny look too, and a remark along the lines of, "Well, I hope you like drinking." ;p Haha.
