They are not going to find him, so he better get moving. A small liberal arts and science school is a great idea, but I am biased.
Mike our first trip was to various schools in between Chrismas and Nyears 1-1/2 years before he graduated. He was close enough to be of interest to some schools, but not too far away to waste their time. My son emailed the coaches (with a profile so they knew what they were dealing with) that he was visiting and some actually came and met us, some said they could not be there and helped us organize our visit and some never responded. So we hit 5-6 schools in a few days and made a mini vacation out of it. There was not much campus activity but it helped him formulate an opinion. We had also casually visited some campuses the summer of his Soph year on our own with no contact with anyone We also visited some schools while doing combines, camps, and tournaments his Jr summer, and he then did some official visits in the fall/winter of his Sr season. (he committed on May 1st)
