2017: great company, decent weather, just had a good laugh all weekend. Saying that, although Radiohead are probably my favourite band, I'm in the camp that didn't actually enjoy it that much at the time, something just didn't click
2013: first time, loved it.
2014: solid year
2022: crashed my car on the way down on the Tuesday
2016: muddy and felt ill for most of it. As others have said, vibes were off after Brexit vote.
Funny how in retrospect the bands you've seen are not that important, it's the 'macro' factors (weather, company etc.) you remember most
