I keep mine private. I use my logs as personal entry logs and have things in there that don't need to be in the public eye. I didn't realize I could filter out what I display publicly, if I truly can then I might make mine public (but probably not). I don't read other peoples journals just coz I figure if someone wants to share something, they'll post it as a thread. Since I ride the vast majority of the time alone, I guess it just doesn't occur to me to compare my stats with someone else.
Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, champagne in one hand, strawberries in the other, body thoroughly used up, totally worn out and screaming: "Yeah Baby! What a Ride!"
