Good luck, bearing in mind that you have been going up there for a while, you may feel as comfortable as i do where i go, been going there since i was 14 :!:
If i know the majority of doggers like i think i do, from being alone and with my wife, then you should be ok. I have never encountered any probs, had a few wierdos, but they were quickly moved on by the rest
The only concern i would have if it was my wife would be someone wanting you all to thenselves, and going to any means to see if they can get their way :!:
Not that i would let my wife do it, i would go with her, but be in the background so i could keep an eye out (one of my fantasies lol)
