Assemblies in my youth were roll up in your car. Park your car were you liked right next to the ground/stadium in a field -- then set up a comfy camp with your deckchairs/tarp etc
Then after midmorning the smell of the bacon baps used give us the incentive to hang in till the generous lunch break -
It's all changed now - i don't miss assembles and i am so glad I will never have to attend another one ever.
