Generally not a good idea. Most people are usually scared of them. Unfortunately for us and our hobby we are constantly under attack by such people, this makes it extremely important to consider the image you give our hobby by walking about in public with your snake. You may not see it as a big deal but someone who is not into snakes can view it as a irresponsible aspect of our ownership. If I want to take my snakes outside I will just bring them out in the backyard. No need for me to go out in public when I know 95% of the population is irrationally fearful of them and probably don't want to be forced into close proximity with them.
