This photo courtesy of wikipedia gives you some idea of the height
Approaching the aqueduct heading towards Trevor I almost bottled out.
and it's a L O N G way down
I couldn't bring myself to look down the other side of the boat but looking out across the footpath and railings wasn't too bad.
It was almost like flying
On previous crossings I've hidden inside the boat but I'm really glad I made the effort to do it
can you tell I was quite chuffed?
