Didn't have to - my polls close at 9 PM, I got there around 7:30 PM, and my voting station is in a really small town. It's just a hassle because I had to get out of the city, and I have to wake up damn early tomorrow to get back into the city before my class starts. I figured it was important enough to go through the trouble...
The presentations get boring. These aren't the regular lectures, but research presentations - "work in progress" seminars for the most part. If you're familiar with the subject area then I'm sure it might be interesting, but it's almost like listening to a presentation given in another language for most of the presentations I've sat through. My institution technically isn't a college, but if I say any more than that it'd probably be pretty easy to trace me so I'll leave it at that.
I can see how a person could be desensitized to injecting and killing mice. Imagine having to do that to 20 some mice per week, and that you have a load of other experiments to run at the same time. Maybe you're sorry for that first and second mouse, but how much sympathy do you have for that third or fourth mouse, and every mouse after that?
A computer tech - sounds like it'd be a fun course of study. You may never need to use physics or calculus after those classes, but good luck. Hopefully you'll get something useful out of them
