Swim with the crocodiles

It could work and be a tremendous fun and adventure. The problem however is not really crocs but...people. People are the bad ones, the brainless bunch who often get harmed at their own wish and then blame it at the world. And I am afraid there is no way to be sure that your zoo/place won't let idiots in.

 

Those old alligator shows had a thing at the end where you could get your picture holding a baby alligator, but its mouth was held shut with a big rubber band. I imagine a place doing "swim with the alligators" might do something similar, just with material stronger than a rubber band.

 

Good point about idiots but if we had keepers in with them do you reckon that would work
