If you have older friends who are in college at schools you'd like to know more about, here's a suggestion. Ask them if they'd let you take them out for lunch or coffee when they're home for spring break so you can ask them some questions about their experiences.
If you ask your average college student, "How's college?" in person or over email, but do so in passing, you're going to hear a brief answer, usually very positive without any details. But over lunch or coffee when it's just the two and you have more time, a college student can spend some time telling you what he or she really thinks. And you can ask as many specific questions as you'd like.
And offer to pay for their coffee or turkey club. They deserve it for taking the time to help you out.
