If you have the luxury of vacation time

Chances are if you've lost your job you're not thinking about scheduling a vacation, but if you should have the time and the means check out vocationvacations.com 

They call it test driving your dream job. Basically, what you get to do is work with someone already doing a job you're interested in..."a total immersion." You get to work one-on-one with someone living the life and see the job first hand.

Sounds pretty cool and a good way to combine a vacation with a job search.
