It is not a great idea to have snakes out in public especially unannounced. It may attract attention but sometimes you can attract bad attention. Some people like snakes while alot don't. It only takes one that doesn't to start some type of ban or negative affect.
In the late 1980's in NYC I would see a few people carry their 6-8 boas and burms to parks and public events. I never took mine out to be publicly displayed. As every year pasted more and more people brought their reptiles out because they saw the attention they got. Some people scared others with their snakes intentionally. In 2005 boas and pythons (burmese, boa constictors, ... the bigger snakes) became banned. I wonder who could have sparked that fire. My first and favorite Reptile Store shut down after decades of being in business because of this.
You don't want people knocking on your door when their toy dog is missing and your boa is nowhere to be found...
Even though your intentions are probably innocent. Be more responsible with your PD of your snake.
