Some lessons learned from this chart:

• You can only enjoy snow so much (there seems to be a limitation on possible enjoyment), though that amount seems possible to increase with the correct sled.
• Sleds seem capable of turning potential energy into kinetic energy and happiness.
• Nobody likes going to work when you expected a snow day.
• Staying in can be fun, but exploring is even better. AKA the “Calvin and Hobbes” Principle.
