The weather report, that is.
I used to check the weather report when I got up in the morning. Thunderstorms, rain, high heat, snow etc were all good enough reasons for me to go back to bed for another hour once a week or so. Invariably, the weather wouldn't behave as predicted, and I'd end up driving home in what would have been awesome riding conditions.
So I stopped looking. Now, I'm just carrying the rain gear all the time just in case, hanging out at the office for an extra 30 mins every now and again to let the lightning pass, and riding every day.
Anyone else a slave to, or been a slave to, the weather forecast?
