I guess I've been lucky. My first born is now 8-years old, making this my 7th Halloween going around the neighbourhood taking him trick-or-treating. I've always taken note of how seasonably warm each of these nights were, and been grateful.
They're calling for a high of 7°C tomorrow, but it'll dip to 2°C by the evening. That's friggin' cold.
Oh well... this is Halloween.
