We have the same kind of laws here in Dartmouth, Nova Scotia. We can not have venomous snakes, Snakes over 2 feet at their adult size, no scorpions or spiders.
But just across the bridge which, is not that long at all, takes you into Halifax and they have no bi- laws like this.
I really can not understand it but thats the things are.
We keep bigger snakes anyway, we just do not tell the wrong people about it.
