I was also very surprised by the negative comments. I found it very useful to be told the status of an airfield that I will be going to in the next few weeks.
There are many times when I have found PPR very helpful and glad that I did make the call. The last airfield I went to was not PPR and I ended up having to be towed out the mud by a tractor.
If you don't have any interest in Sandown airfield then why bother making a comment at all.
