I put an application in for a ride out quite a while ago but haven't heard anything since? I know that Sally was also looking into it for me but wondered if they were still on going or have they been cut back?
Going on from there has anyone done one recently? If I get the chance to go, are you provided with anything, do you have to sit there and not get involved or say anything should anything occur? Should you take anything with you?
Being in Shepton Mallet, the local nick is closed so its not as though I could just pop in at anytime, to ask.
I think it would be great to get on one just as a taster for whats involved and what to expect.
Any comments would be appreciated. 
I remember my first Observational Shift, was very nervous, didn't know what to expect. Thought I would get in the way, but I was made very welcome and loved every second of it, stayed the whole shift.
You will get a Officer brief you on the does an donts, health and safety, and what to do if it all kicks off.
Like CJay said, these are invaluable, and will help you during your recruitment process. Take this opportunity to ask any questions about the role of SC/PC.
I've been waiting five weeks for my third Observational Shift, just sent a email off and had a reply within minutes. Being chased up as we speak.

Things do take time as they're very busy, but it's always good to send a "polite" email asking for an update.
