The concept was imported into the UK by 2 people who discovered the activity whilst on holiday in France.
It seems that Go Ape has been a great success and is now developing at a fast pace on this side of the Channel.
My wife (fiancée at the time) having tested it during The Day I wasn't allowed to gate-crash, organised a trip to Thetford Forest along with colleagues and friends.
Despite my initial fears about the vertigo issue, this problem proved to be unfounded and I have to say I really enjoyed myself. It was actually more technical than I expected (you go quite high and you really don't want to mess-up too much with your carabiners!) but you soon get used to the double "attach-detach" sequence.
Was it because of the "made in France" on the pulleys?
But even on the highest points, I felt safe and confident.
Simon, organiser of most of the cycle rides I have done, has released a very good short film about cycling in Cambridge.
As a cycling commuter myself (80% of the time. If I don't use my bike, I walk), I cross the city every day.
It is a very well balance report of the existing (good and bad), the past, present and future of the facilities. Simon recognises the fact there are "cyclists" who don't care about lights nor cycling the wrong way (and due to their selfish behaviour they are unfortunately the most visible ones) but also that there are far more cyclists law abiding who suffer from the generalisation: Cyclist = dangerous law breaker. Specially when used as an excuse by police and local authorities.
