What is the best CNA position???!!

I apply to nursing school this summer and of course it looks good to have CNA experience. Lucky, I am in the position to be able to choose which area/floor of the hospital I would like to work as a CNA. I realize that CNA's basically do all the dirty work..but is there any area that you would consider to be more "easy" or "fun" than others?

If anyone can tell me about any positions that you have done or enjoy, along with what they are responsible for--that would be great!
