Deano,
Brilliant field, however I did find it a little tricky to spot at first, used to strips of black, I guess!! The gasometers at Reading are very easy to spot, so you should have no probs there and WW's runways are quite smooth in comparison to Compton Abyss. I'm was in the same position as you before I went, but had no probs.
Staff at the field are excellent and the clubhouse is a real gem!
Best have a look at the website, which is v.informative and give them a call.
