The first time I was in Boulder, it was spring break, I hit the CU weight room, and I was like "hey, there's a good mix of ethnic groups represented." Then I remembered it was spring break, and all the locals go home. And Colorado is still incredibly white. The next time I was in town, it was white bro city. I showed up at the gym with my coworker and ex-coworker, we're each of totally different races, and we all lifted together. As you may have guessed, my interactions with CU students are 99% limited to the rec. center :(. Spent all my time on East Campus, away from most everyone. Beautiful campus, scenery and facilities are A++, but the homeless problem, cost of living, and general ignorance of the majority is a serious issue. Sadly, the YikYak scene reflects the populace relatively well, especially in that age demographic. So beyond a shadow of a doubt, I can confirm that you've never bullshitted anyone about how bad it can be there. Oh P.S. there's 'roids all up in that gym, Jesus.
