I was a cub and it was a very mixed experience. We had some good leaders and got to experience some quite cool stuff: wide games, cooking outdoors, camping. But the
Arkela, Arc main leader was quite an elderly lady who hadn't really accepted WWII was over (this was in the 1980s I hasten to add). It was very authoritarian and quite right wing. We had inculcated in us some very suspect views of non-White people which ranged from the patronising (noble savage) to the overtly racist.
A friend of mine persisted with it and was later a Scout which he enjoyed enough to eventually become a leader. It's a shame I didn't carry on because my problems were very much with one individual. But hey, that's the sort of thing you realise with twenty years hindsight!
