Or a bee getting stuck in a helmet vent and stinging you on the forehead. (Though I'm sure getting stung on the eye would be just as fun.)

I love

.... thinking your extra fast and that your ride was no big deal (and then realising the wind has been at your back the entire time)

.... getting up that big hill that seems impossible when your tired.

I hate

... couples holding hands and taking up both sides of a bike path, oblivious to everything around them.

.... cars that are severally confused by the presence of a bicycle.

Love:

-observing the ducks and birds in the marsh area on the first :15 minutes of my commute.
-"magic hour" lighting at the end of the day on my ride home. Sometimes I stop to take a photo.
-my work hours vary, but I'm starting to recognize some of the people I encounter on my commute and say hello or wave.
-passing cars when car traffic is bad
-tailwinds
-saving money on gas and not contributing to car exhaust in the air
-getting exercise while traveling rather than sitting and getting a stiff back
-more opportunity for interesting experiences & observations. I used to bike commute into San Francisco daily. As the sun was setting, while riding on the golden gate bridge, I passed a guy biking with goggles and a cape and he had a backpack with a small dog in it - and the dog also was wearing goggles and a cape. More recently, I took a trail shortcut through the marsh on my way home and encountered cops heading out to remove homeless people that were sleeping in the marsh. I definitely have more "interesting moments" when I cycle to and from work.

Dislike:

-any significant wind that is not a tailwind
-debris and broken glass in the bike lane, especially on my way to work when this makes me anxious about getting a flat and then being late for a meeting.
-stoplights that don't detect my bike. I recently contacted a city traffic department staffer about one particular light and he said this: "you just don't have enough ferrous metal on your bike to set off the light." Cyclists in my area get $500 fines for running stoplights and stop signs.
-Running late and having to get dressed really quickly when I get to work and then scrambling to my first meeting while still a bit sweaty and then realizing my sweater is inside-out in the middle of the meeting...
-professional dog walkers on the bike path walking five dogs at a time, all on retractable leashes...
-trying to pass pedestrians with loud headphones on

I love:
enjoying my ride so much that I miss my turn and have to cycle farther.

I hate:
getting annoyed that I missed my turn.

Love-
Being on a bike.
Going downhill.
The smell of Lake Merritt.
Getting exercise.
My own personal transport. I don't own a car so its bus or Bart(train) for me.

Hate-
My current grips are hurting my hands.
Buses.
Horrible International Blvd. Potholes.
Not having a front brake on my bike, skidding to a stop sucks.
