I went along for a few hours yesterday and had a reasonably enjoyable time.
Personally I felt that it was not as good as past years, for me at least there were far too many holiday firms taking up the stands, I have nothing against this at all but its just a shame that there seems to be a bit less in the way of book stalls, main camera dealers, wildlife study equipment than there used to be.
Having said that it was good to catch up with some old friends and have a good browse in the optics marquee, I also came away with a couple of new books that I wanted and it didn't rain whilst I was there there.
