Crocodiles & wheelchairs don't mix

Sometimes signs can be very misleading...
Generally when there is a warning sign or if something is prohibited, there is a very distinct line through the sign, drawing your attention to the fact that the behaviour depicted is either illegal, or simply not a good idea.
In the case of the sign above (which I found in a crocodile park in St Lucia) the sign seems to defy the usual standards of signage and in fact seems to encourage the depicted behaviour.
In short, the sign seems to say: if you are accompanied by anyone in a wheelchair, please push them downhill towards the waiting crocodiles and ask them to scream open-mouthed on their way down.
Unfortunately, I was unable to comply with the sign due to the fact that there was a lack of wheelchair-bound individuals at the time.
Pity...
