I actually have one of my BPs in with me at work today. I didn't feel like making an actual costume so I decided to come as the "crazy snake guy" lol. She's actually been a huge hit here! Everyone except for one or two people love her and can't believe how sweet she is. As far as having them out when the trick or treaters come by I would say try it for a little bit, I mean you'll be in your house right? You can always just go put them away if they start getting too cold or if people give you a hard time. But I don't think it's true that "99% of people doesn't like snakes". I actually just helped one of the girls get over her lifelong fear of snakes! She's in her 50s and has never held or really looked at a snake and she was just now holding my Selene and saying how beautiful she was and how cool they are lol. So I'd think it could be sort of the same with those kids and their parents, I'd think they'd be more curious than anything.
