We have a wheelchair user racing at Wycombe twice a week (every Saturday and every Monday evening) and it takes 3 guys less than 10 seconds to lift him up a set of steps and down again at the end of the evening. This has been done for years and years, never a problem.
At Swansea there were only 1 straight set of 8 steps, you had 50+ guys there that could have helped, all you had to do was ask.
It's really starting to look like you are just out trying to cause hassle with some grudge to bear.
