For the first time yesterday I put my I-pod in my pocket when leaving the gym. I said the heck the with it and put the head phones on under my helmet for the ride home. WOW!!! Beautiful 95 degree day. Nice country road.... When Janis Joplin started imploring me to take another piece of her heart.... the moment was about as good as any can get!!! Then I looked down at the speedo and saw I was doing about 85+! Same reason I don't listen to music while skiing, it's kind of neat, but not a good thing not being able to use my sense of hearing to judge my speed. I'll do it from the gym to home, but can't see ever doing it on the open road.
