Taking the cellphone, I feel better about exploring new routes, going longer distances. I generally leave it turned off and only have it for the extra security. It has definitely come in handy! Unfortunately, I've had a couple accidents on the bike and the cellphone was how I got the help I needed to get to the ER. So, I feel safer having it along than not. It also allows me to check in on the kids at home if I am out for a long time. Overall, I think cellphones are a great convenience. one of those things that, once you get accustomed to having, you wonder how you ever did without it.
