Displays here switch on around sunset. In Morrison that means about 4:37 PM in early December and 4:37 PM by mid-month — the earliest sunsets of the year fall right in the middle of lights season. It is properly dark by about 5:08 PM, which is when the displays look their best. December nights in Morrison typically drop to around 16°F.

Practicalities
Residential displays have no facilities of their own — no parking, no toilets, nowhere to warm up — so it is worth knowing what is around. Within about three miles of the Morrison cluster, OpenStreetMap maps 3 public car parks and 13 public toilets. Only 3 cafés or takeaways nearby, so bring a flask if you want one.
