In my opinion yes there good festivals, some I have enjoyed when I was there and some maybe just looking back at.
Started my festival career just after my 18th birthday at Reading 1980, went to Reading for four years moved on the Glastonbury mid 1980s, started going to Cambridge Folk Festival, for the next 20+years, continued going with young children, different experience I never knew festivals had story telling and circus workshops!
Moved on the family friendly festivals, Wychwood at Cheltenham racecourse, now that's middle class for you, Lakefest complete with the children field organised by horse drawn traveller types. Meet people, discover new music, meet friends who you only know at festivals, drink cider, leap around with aging punks, rockers and others, what's not to like. Yes there are good festivals still and only two weeks to my first of the year.
