What's a "college fair"?
College fairs are often groups of colleges that come together and rent out a large space such as a convention center in a large city and tables are set up. Admission officers are present. College representatives are present and they put out brochures for students. It's really quite a wonderful thing for students to expose themselves to different schools that way. First of all, it gives students experience in speaking to admissions officers. It gives students an opportunity to ask some important questions about specific schools. And it also gives admissions officers a chance to meet students face to face instead of just looking at a paper application or an online application.
