Caldwell is just over about 27,000 residents, and this is the only college. It has a student:faculty ratio of about 15:1. This is a private school, so it costs a bit more than other schools in the area. Northwest Nazarene University is larger, and so is Boise State Universty, which has a lot more.
This place is a lot bigger than where I grew up. I went to a high school where kindergarden through 12th grade was just over 125 students. I graduated in a class of 11, and here it's a bit over 100. So it's bigger to me. But, yeah, Boise is where most of the action is. (And I do mean action. There's almost 20 strip clubs, and a dance club.)
