I run timing at Stateline Rallycross events in the midwest for the past 3 years now. In those 3 years I've seem some interesting things and had great experiences.
If you're ever in the mid west, check out a Stateline Rallycross event. http://statelinerallycross.com/
Even though it's very hard and long work with little monetary value, the most rewarding thing is seeing the pure joy in the drivers faces after the event. They're still on a high from the racing, I know the feeling.
