At around 11 or 12 I had moved from Fulham out to Twickenham. Mates and I in the holidays would buy Red Rover tickets from the Fulwell Bus Depot. The cost two and six in old money. (12.5 pence) These enabled the purchaser to travel anywhere using a red London bus for 24 hours.
Duffel bags stuffed with sandwiches and orange juice kept us fed and we would travel all over London.
We visited so many places that now are the preserve of tourist and at that time they were all free.
The Science Museum, The Natural History Museum, The War Museum, were favourites. The Tower of London, where we walked past The Crown Jewels. (we may have had to pay to see them) The Monument, which we climbed to the very top, St Paul's Cathedral, The Cutty Sark, Greenwich Observatory and places I can not even recall now.
We would get on any bus and go for maybe 10 or 20 stops and get on the very first bus we saw and repeat that again, and again until we were God knows where. With the trusty London Transport bus map we always found our way back home.
East to Epping Forest, West to Windsor and Castle, South as far as Dorking or Leatherhead, North as far as the buses ran. We would start at 8 am and get back home between 6 and 8.
No phones, no worries. just out with your friends and out of touch.
Happy days.
