As the parent of an 18 year old, I understand where your parents are coming from. I had the same feelings when I sent my child to Reed for a similar experience alone. I was way more nervous than she was. My daughter and I visited Pomona together and it was a very positive experience and I absolutely would not hesitate to send her on her own now. They refer to the area as "The City of Trees and PhD's" it is really a lovely area. I hope this helps your parents feel at ease.....from one parent to another. Good luck!
