One of our sessions was a computer GIS session. We did something with some GIS software -- coloring counties based on percentage of some demographic. I finished in about a quarter of the time allotted, and spent the rest of the time talking to the relatively cool TA.
"You should really look into computer GIS stuff. There's a huge field out there."
"Oh, I'm really mostly just interested in web development stuff."
"I'm telling you, get into GIS. It's where it's at. You'll want to be there in 5 or 10 years anyway, should get ahead of the game now."
Of course, I'd never want to do anything with mapping on the web. That just wouldn't make sense.
