Enough to know I dont like doing it.
Enough to know I really dont like doing it in single digit temps with wind blowing.
Enough to know doing it on a country road when its raining isnt much fun either.
Enough to know the shoulder suddenly doesnt seem quite so wide when your a$$ is about a foot away from 70+ MPG traffic.
To sum up...
Enough to know I dont like doing it.
