Youngsters and or newcomers would get a slightly rose tinted view with most of the feedbacks we leave tis true.
Partly due to the sentiments held by Chalky's Nan that we all/most have, but also (perhaps) the thinking of I'm not the kind of chump that would blow a load of dough and travel hundreds of miles for something that's crap - I know better etc..
That said we've all been to crap do's. The way to read between the lines with look backs is, where's there's 2+ pages of comments with everyone raving about it - it was probably good - verses 17 replies and "numbers were a bit down, but all the dj's gave a good account of themselves" = it was crap.
Not just the written word either, it's a brave man or women that'll take a pic of three dancers on a massive floor - more that lot huddled in the corner - if any!
