Just a question?

I live near BHX and tommorow i’m going there for a few hours tomorrow with my new digital camera.
I’ve went there before and i know there is a dedicated viewing area in the Aviation Experiance but the problem is it’s inside and photos can be obscured by the sometimes dirty glass, there used to be a small parking area on the A45 road going passes which is good for approch and departure photos but i think it may be closed off so is there any other areas in and around the airport which is good for taking photos?
thanks:D
