I haven't read alllll of the posts here, but I wanted to give my version of events in Pennards on the Friday night. I'll start by saying it has not put me off going again at all!
This was my 11th Glastonbury, we've always camped in Pennards and in the last 6 or so times, in the same place- just over the hedge from Arcadia. It's busy, it's fun, it feels safe even if it is busy. This year, I went home early on Friday to have a lie down as I've got a broken rib and it was giving me jip. Got back to camp to find millions of people swarming through the campsite towards Park/Arcadia! Thankfully my campmates were home, as were some of our neighbours, and we spent the next goodness knows how long hanging on to our tents so they didn't get trampled. I daren't bend down to fix my front guy lines for fear of being walked on myself! It really was the only time I have felt unsafe there.
Most people were polite and tried not to tread on our houses, but I'm not sure my tent will do another festival as it was trampled around the edges. Not half as bad as some people near us had. A few people were extremely rude though, and shouted at us for trying to hold on to our tents! I ended up ringing the police as we seriously thought we were in danger.
After a while the crowd dissipated and we were ok, but really, singular most scary moment at a festival ever.
