I personally keep monitors for what they are...monitors. I do not subject my animals to handling(only when medical attention is needed), or bringing them out into public. I see that as being a significant way of stressing an animal out..
Bringing an animal out into the open, with bigger animals(us people) looking, staring, gazing, reaching out to pet, etc... This poor animal is then fearing for its life.. Animals in nature do not (in most cases) stay out in the wide open for long periods of time, otherwise, it'd basically be saying, "Hey Mr. Kestrel(or other predatory bird, or predator for that matter), come on down and have me for luch..." Monitors prefer to take refuge in tight fitting areas, in the forms of tree hollows, burrows, cracks, fissures, etc... I bet if you put your animal down without a leash, he'd book for the closest bush, log, clump of grass, etc...
I just feel that taking monitors out in public, handling them, and putting them on display(not talking about zoos) in front of many big animals(people) is a bad idea... Once again, I think people are mistaking reptiles, especially monitors, for animals like dogs, who are accustomed to interaction with humans...
No matter how tame your animal is, it's still going to have the same instincts, which is to always be alert, and be wary of predators... I'd be scared as hell if I was brought out into the open, without anyplace to hide... while much larger animals are walking around in the vicinity, that could easily spot me...
Just my thoughts on the matter..
