My snake is happy in his home, I see no reason to take them out and about other than to educate kids, and even then it shouldn't be done very often or at least with different snakes each time in a short period.
Expo's on the other hand only happen once or twice a year, which is perfectly fine! You still may get one or two of your snakes that wont eat after being to one though.
If you do take him out and he poops on you its his or her way of telling you I told you so!![]()
