This is a brilliant topic. Nostalgiafest. Love it!
“Book and skate” down Dog Kennel Hill near Dulwich Park Sarf London: take old hardback book, foolscap size or larger. Put it on single roller-skate. Put self on top of both. Point downhill. Push off. Scare living daylights out of self and people waiting at bus stop. If you had any skin left on knuckles you weren’t doing it right!
Anyone remember Mivvies?
