I look for a hostfamiliy in the USA 2009

Hello my name is Sandra. I’m 15 years old . I live with my parents ( they living apart) , my sister (13) and a cat
in a little town (35.000 inhabitans)in the near from Nuernberg in Germany and the people here are very friendly, so it’ s a nice place to life.
I’m going to a secondary school there. I’m in the 9. class.
In my spear time I riding horses since 2 years. I’m going for a swim and I listen to musik .
I´m looking for a family who has a boy/girl in my age (nearly) who host me for 3 Month, give me the possibility to take part in the school-system. After that, I and my family will host the boy/girl for 3 Month , to participate in German life and schoolsystem.
Because its my bigest desire to live in the USA for 3 Month. I dreamd about for a long time and I hope a hostfamily can accomplish that.

I look for an answer
nice gettings
Sandra
