Ask HN: How to find summer internships in the city?

I live in a small town in South Carolina, I've been dabbling in web stuff since I was 12. I was lucky enough to learn the right way to do things on the web. I ended up teaching myself HTML/CSS and growing my freelance business in my town developing web sites for businesses. I am now a senior in high school and I want to go out into the "city" and work somewhere that will help me further my abilities and passion. I don't really care where, just in a decent sized city that has a lot of opportunity. I'm ready to get out and explore. Any help or advice would be appreciated.
