Discover University - Share your screenshots!

I haven't bought this pack yet.. I definitely wanted to see other people's opinions and experiences, considering some of the other packs that have flopped or at least had some flaws. Just curious, as I scroll through all these screenshots (thanks for all of these, btw, everyone!) can you ride a bike... without a helmet? If they made it some default that your sim has one while riding, I'm hoping for a mod eventually that lets you go without it...!
