I'm sure that I'm missing some, but here goes...

Hide and Seek

• Where's my lane? (played on snow covered roads)
• Where's the road? (played during snow storms or blowing snow. For extra challenge, play at night)
• Where's my car 1? (played after the snow removal guys have towed your car to some unknown location)
• Where's my car 2? (played in large parking lots, after snow has covered all cars. Persons with car beepers are not allowed to play.)

Gambling

• Can I start my car? (on very cold mornings)
• Should I leave my car running all day, or will I run out of gas? (variation of above)
• Looking cool. (How long can I survive without my hat/gloves and winter coat because they don't flatter my image. - Popular game among young adults and teens.)
• 4-way Stop
( ... or 'Is that fool able to stop or should I just let him slide through the intersection before proceeding?')
• Pass snow-plow on highway.

Slalom

• Drive with all-season tires. (s/all-season/no-season/ because they ain't good in summer, ain't good in winter)
• Sidewalk walking.

Body Building

• Moving snow...
  • out of driveway
  • off of car
  • off of street leading to center of road which may be plowed.

Spectator sports

• Watch snow-removal operations.
• Watch people attempt to drive up steep hills. (played when streets are snow covered)

Interactive

• Rent movies set in warm countries, and whine.
• Complain to others about how cold it is, but always remember a time when it has been colder.
• Laugh at other cities who come to a screeching halt when snow accumaltion exceeds 3cm.
• Use common greeting "S'cold eh?".
