@bwcafan, my husband and I are both Carleton alums, too. We have several children and the idea that another college might be a better choice for them was at first hard to fathom! But in the end, it was so much fun getting to know other schools. Still, I’m not sure I could have accepted an Ole in the family… 
Our youngest was admitted to Carleton and will be at Accepted Student Days in April. This was unexpected. She had little interest in Carleton until she visited, and then it worked its magic.
