I don't know where you live, but my sister had the same question. I told her to talk to the CFRC and they set her up with a LogO to talk to. Kind of a job shadow... I don't know if the CFRC would want to start entertaining that idea. But it does show initiative, IMHO. Personally I know how you feel, You can read all day, but to actually see where you will live, what you will do, how you will shower, etc, etc. It's a hard choice to sign on the dotted line. Police, ambulance and fire (for the most part) will take you out on a ride along, would be nice if the CF could accommodate as well.
I know that the NOAB has flushed a couple potential candidates on their own will, due to physically letting the terms come to grips. It either confirms your choice or brings you to the true reality.
If pictures and reading was good enough, I would never have to go on sight seeing tours in europe.
Wish I personally knew a NES OP for ya. Good luck
