Kevelaer German Trip

I am a farm kid from Kansas.  I have studied the German language for 3 years in my small high school.  I have the opportunity to go to Kevelaer Germany and would love to go.  I am a history buff and would love to visit historic sites in Germany.  My dad is a farmer and my mom is a local biology teacher.  We are trying all kinds of fund raising to help with costs as my mom would also like to travel with me as an adult sponsor.  There are about 20 of us traveling to Kevelaer.
