Signs of life

From DrinkiWiki

I've only played it in Chicago, but you can play it pretty much anyplace with a public transportation system that runs above ground.

Get on the Brown Line el. When it gets up north, to the part where you're an arm's length from the buildings (or would be, if the window were open), start drinking whenever you see signs of life.

People in the windows, people on the rooftops, pets, unattended grills, etc.

1 drink for seeing a person or two.
1 drink for an animal
1 drink for unattended grill or any project that looks like it's currently happening though unattended (gardening, etc)

2 drinks for naked people (any number), or people who look like they will soon be naked (use your own judgment)
2 drinks for a group or crowd
2 drinks for anybody waving at you

End it when you're at the end of the line, or when you've ridden all the way back and are at your original stop.
