Writer is pretty much right. I don't ever take a snake in a public park and let it go. They don't respond at all as mammals do. Plus, there are the environmental concerns, anything the animal may pick up there. Things that the native reptile population may have evolved to deal with they may be harmful to that species. For example, the snake mite, Ophionyssus natricis, has become common in reptile collections all over the world, and in wild reptile areas all over the world, and the one thing biologists have discovered, is that they are not native to most of those places, and noone can say with certainty where they are originally from or what species are their original hosts.
And to top all that off, you have to worry about animals there, I really don't want amy of my snakes messing with a wild squirrel, etc. Then you always have to worry about public perception. Since all the media hype on the burms in the glades here in america, many people have gotten very ignorant about snakes, and many people think a 4' python is going to eat their 8lb toy dog breed. Or their toddler. It's amazingly stupid.
I have occasionally let mine play on a tree on my own property with me watching, but I have to collect them most times.
