So you know you are having a GREAT ski day when:

1. From the chairlift, you hear yelps of "whooohooo" "yeeeaaaooowwwww" and "iiiieeee" from the skiers below.

2. You stop, and you can no longer see your skis.

3. Doing high fives with skiers you don't know seems like the right thing to do.

4. The "singles" line at the chairlift is huge since everybody has abandonned their group because there are no friends on a powder day.
